a Golf ball of with a mass of 45g and diamter 4.3cm reach terminal speed when dropped from a height of 25m, the drag coefficient is 0.35 and the density of air is 1.2kg/m^3.
using the formulavt=sqrt(2∗mgCpA)
vt=sqrt(2∗(45g)(9.8m/s2)(.35)(1.2kg/m3)(0.043m))
so pluggeed that into my calculator, and found the terminal speed of 220.99m/s.

What is the terminal velocity of a bouncy ball?
The terminal velocity of a bouncy ball depends on its size, weight, shape, and the air resistance it encounters during its fall. Generally, the terminal velocity of a bouncy ball is low compared to heavier objects due to its low mass and streamlined shape.
When a golf club strikes a golf ball the force exerted by the ball on the club depends on?
the mass of the ball and club and the velocity of the club
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.
If a bowling ball and a golf ball are moving at the same velocity which one would have more momentum why brainly?
The bowling ball would have more momentum because it has more mass than the golf ball. Momentum is calculated as the product of an object's mass and velocity, so a heavier object moving at the same velocity will have more momentum.
When a golf ball is hit its momentum is due mostly to its what?
When a golf ball is hit, its momentum is mostly due to the velocity and mass of the ball. The velocity of the ball at impact, along with its mass, determine the overall momentum of the ball as it travels.
What falls faster a golf ball or a table tennis ball?
The golf ball will land first. All objects fall at the same speed, but that's in a vacuum. The ping pong ball has a huge amount of drag (which is air resistance) for its weight, so it will be slowed enough for there to be a visible difference.AnswerThe golf ball will reach only a second or so before the ping pong ball. The chair will not be high enough for the ping pong ball to be considerably slowed due to air resistance.
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
Can an elephant have the same momentum has a golf ball?
No, an elephant cannot have the same momentum as a golf ball. Momentum is dependent on mass and velocity, so even if an elephant and a golf ball were moving at the same speed, the elephant's much larger mass would result in a significantly greater momentum.
What is most important in golf ball distance the velocity of the club or the mass of the club?
mass of the club
Can an elephant have the same momentum as a golf Ball?
Momentum is the product of the mass and velocity of an object. Since a golf ball has a much lower mass than an elephant, it would have to have a much higher velocity to achieve the same momentum as an elephant. But it is definitely possible.
Which one would go faster with the same kinectic energy bowling ball or a golf ball?
The golf ball would go faster because it has less mass compared to the bowling ball but the same kinetic energy. The kinetic energy of an object is determined by both its mass and its velocity, so the lighter golf ball would be able to achieve a higher velocity with the same amount of kinetic energy as the heavier bowling ball.
What moves faster a ball thrown down or a ball falling down?
A ball thrown down. The thrown ball will have a greater initial velocity and since they experience the same force of gravity, it will always be faster (until they both reach terminal velocity).
