A juggler throws a bowling pin into the air with an initial velocity Vi another juggler drops a pin at the same instant compare the accelerations of the two pins while they are in the air?

Since the question is asking you to compare the acceleration after the pins have been released, the only force acting on each pin is gravity. Therefore, the acceleration on both pins is the acceleration due to gravity, or 9.8 m/s2 towards the earth. Even though one of the pins is being thrown up, once released, the acceleration is still 9.8 m/s2 towards the earth.Each pin has the same acceleration.

What two quantities did Edwin Hubble compare to discover the expansion of the Universe?
The Serperation of Galaxies which was caused by Dark Energy, and the Big Bang.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity of a black hole is equal or greater than the speed of light, so light cannot escape
What is the density of a 200 g mass bowling ball?
Ten-pin bowling balls usually weigh from about 6 pounds (around 2800 grams) to 16 pounds (about 7200 grams) There are no bowling balls that weigh 200 grams (though such a ball would be leagal as there is no minimum weight) but if there were, the mass of the ball divided by the volume of the ball gives the density. The volume of a standard bowling ball is about 5500 cubic centimeters (I assumed a circumference of 27 inches and calculated from that) 200 / 5500 = 0.036 g/cm3 Compare to the density of air = 0,0012 g/cm3
How would two atoms from the same element compare with one another?
the size
How do you calculate the friction in a pulley?
To find the velocity ratio of a pulley, you must first find the effort and load distances. then you divide the two and there you have you VR (velocity ratio).
Is it possible for an object to have zero velocity?
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
Compare the speed of a moving golf ball with the speed of a moving bowling ball if both balls have the same amount of momentum?
momentum=velocity x mass say a golf ball weighs 1 pound and the bowling ball weighs 5 pounds the golf ball would have to be moving 5 times faster than the bowling ball to have the same momentum
How do you compare velocity and speed?
Velocity is a vectorial quantity, speed with a direction.
If a golf ball and a bowling ball collide and the bowling ball keeps moving How did the golf ball's speed compare with the bowling ball's speed?
The force of the bowling ball colliding with the golf ball causes the golf ball to be redirected in an elastic collision. How fast either travels depends on the friction of the surface and the angle of contact with the bowling ball.Comparative Masses and EnergyIn the collision between a golf ball and a bowling ball, the fact that the bowling ball continues to move (although possibly changed in direction) is a function of the comparative masses of the two. The bowling ball is much more massive, so at normal velocities its kinetic energy exceeds the kinetic energy of the golf ball. In order to "stop" the bowling ball, the golf ball would have to make a perfectly aimed collision, and have a much higher velocity. Quantitatively, the velocity of the golf ball would have to be the inverse ratio of the ratio of the masses of the two balls, so that the kinetic energy (mass times velocity) is equal and in the opposite direction.Example : Golf ball at 45 g, ten pound bowling ball at 4500 g -- the golf ball would have to move at 100 times the velocity of the bowling ball to counteract its kinetic energy. If the bowling ball rolls at 2 m/sec, the golf ball would have to travel at more than 200 m/sec (720 kph or 447 mph), about 3 times a ball's normal velocity off the face of a golf club.
How does the direction of momentum compare to the direction of velocity?
well if you compare them together they are quite different velocity has a poo in your mouth and momentum like to wee on your dog in the morning, okayy!
How do you compare an elephant's weight on the moon with its weight on earth?
The weight would be in the ratio of the accelerations due to gravity on the surfaces of the two bodies - approximately 1/6.
Is the velocity of 3ms greater than -4ms mathematically?
No. If you are talking about "velocity", then you are talking about magnitude and direction - i.e., vectors. You can't really compare vectors, in the sense of one vector being greater than another; but you can compare their magnitudes - and the magnitude is always non-negative. In this sense, you can't even have a "velocity of minus 4 m/s" - you would have a "velocity of 4 m/s in a certain direction".
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
If a golf ball and a bowling ball are rolled toward each other when they collide and the bowling ball stops how does the golf balls speed compare with the bowling balls speed?
the golf ball stopped but the bowling ball keep rolling due to their different size and weight.as we know bowling ball is bigger in size as well as weight so it will face more fictin force and stops early as compare to golf ball when they collide and at the same time bowling ball poshes the golf ball back.so the golf ball stops and the golf ball keeps rolling.
How do units for speed and velocity compare?
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
Compare 38 special round to 38 p?
If you mean +P, the difference is velocity.
What two quantities did Edwin Hubble compare to discover the expansion of the Universe?
The Serperation of Galaxies which was caused by Dark Energy, and the Big Bang.
