Can anyone assist, I have tried various formulas on both problems with no luck. Thanks for any assistance or feedback.(adsbygoogle = window.adsbygoogle || []).push({});

1) A student (m = 59 kg) falls freely from rest and strikes the ground. During the collision with the ground, he comes to rest in a time of 0.020 s. The average force exerted on him by the ground is +21000 N. From what height did the student fall? Assume that the only force acting on him during the collision is that due to the ground. The answer should be 2.59m

2) A 0.295-kg projectile is fired with a velocity of +585 m/s at a 1.00-kg wooden block that rests on a frictionless table. The velocity of the block, immediately after the projectile passes through it, is +40.4 m/s. Find the velocity with which the projectile exits from the block. The answer should be 352.19 m/s
