How do you find total kinetic energy after an inelastic collision?

Inelastic Collision Two objects that have equal masses head toward one another at equal speeds and then stick together. Their total internal kinetic energy is initially 12mv2+12mv2=mv2 1 2 m v 2 + 1 2 m v 2 = m v 2 .

What happens to velocity in elastic collision?

In a head-on elastic collision where the projectile is much more massive than the target, the velocity of the target particle after the collision will be about twice that of the projectile and the projectile velocity will be essentially unchanged.

What is the velocity of inelastic collision?

Perfectly Inelastic Collision (a) Two objects of equal mass initially head directly toward one another at the same speed. (b) The objects stick together (a perfectly inelastic collision), and so their final velocity is zero.

What happens to momentum when a tennis ball hits the floor?

When this happens, most of the momentum is transferred to the ball on top. Since the collision in this situation is elastic, momentum is conserved, meaning the momentum of both balls right before hitting the floor is equal to the momentum of both balls right after the collision.

How do you find the final velocity of a tennis ball?

By measuring the height to which the balls travel, one could find a more exact value). Since the mass of the tennis ball cancels out, this shows that the final velocity is 11 times larger than the initial velocity!

What is the velocity of a rubber ball on a plate?

A rubber ball with a mass of 0.30 kg is dropped onto a steel plate. The ball’s velocity just before impact is 4.5 m/s and just after impact is 4.2 m/s. What is the change in the ball’s momentum?

How fast does the golf club hit the ball?

The golf club was in contact with the ball for 5.0 x 10-3 s. Find (a) the impulse imparted to the golf ball, and (b) the average force exerted on the ball by the golf club. We know that in 5.00×10 -3 second, a .045 kg golf ball undergoes a change in velocity of 45 m/s.
