β 14y agoSince 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.

β 14y agoBoth pins experience the same acceleration due to gravity (-9.8 m/s^2) while they are in the air, regardless of their initial velocities. This is because the only force acting on them is gravity, causing them to accelerate downward at the same rate.
The density of the bowling ball would depend on its volume, which is needed to calculate density. Without knowing the volume of the bowling ball, we cannot determine its density. Density is calculated by dividing the mass of an object by its volume.

The escape velocity from a black hole is equal to or greater than the speed of light. This means that nothing, not even light, can escape from a black hole once it has crossed its event horizon.
To compare kinetic energy of cars, you can calculate it using the formula KE = 1/2 * m * v^2, where m is the mass of the car and v is its velocity. The car with higher kinetic energy will have either greater mass, higher velocity, or both. Remember that kinetic energy is directly proportional to both mass and the square of velocity.
A highway, as it is a path along which molecules move from one part of the cell to another.
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
Velocity is a vectorial quantity, speed with a direction.
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.
Momentum is a vector quantity that is proportional to velocity. The direction of momentum is the same as the direction of velocity, but momentum includes the mass of the object in addition to its velocity.
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".
If both balls have the same momentum, then the speed of the golf ball will be faster compared to the speed of the bowling ball. This is because the golf ball has less mass than the bowling ball, so it needs to move at a higher speed to have the same momentum.
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.
Acceleration is the rate of change of velocity. It can be computed by dividing the change in velocity by the time taken for that change to occur. Comparing values of acceleration involves evaluating whether one object is changing its velocity at a faster or slower rate than another object, based on the magnitude and direction of the acceleration.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
If you mean +P, the difference is velocity.
Another way to say compare the flow rates of liquids is compare their viscosities.
