Supposed that a bullet having a mass of 0.022kg is traveling at 240m/s before it penetrates a 2000g block of wood and emerges going 150m/s. If the block is stationary on a frictionless surface when hit, how fast does the block move after the bullet emerges? E. Supposed that a 3.00-kg steel ball strikes a wall with a speed of 10.0 m/s at an angle of 60.0° with the surface. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.200 s, what is the average force exerted on the ball by the wall? F. Supposed that a A 55-kg boy jumps from a 2.8m tall tree then lands on the ground. Calculate the impulse experienced by the 55kg boy.
Situation 7. A ball of mass 0.220 kg that is moving with a speed of collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.8m/s.
D. Supposed that a bullet having a mass of 0.022kg is traveling at 240m/s before it penetrates a 2000g block of wood and emerges going 150m/s. If the block is stationary on a frictionless surface when hit, how fast does the block move after the bullet emerges?
