A 5.00-g bullet moving with an initial speed of 450 m/s passes through a 1.00-kg block, as shown in the figure. The block is initially at rest on a frictionless, horizontal surface and is connected to a spring that has a spring-force constant of 900 N/m. The block moves a distance d = 3.34 cm to the right after the collision. Note that the block only starts moving after the bullet has completely passed through the block. IWW d Round...

In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 45 cm thick 350 kg stationary target and emerges with a speed of 1000 m/s. The target is free to slide on a smooth horizontal surface. (a) How long is the bullet in the target (assume constant acceleration)? s What average force does it exert on the target? N (magnitude only) (b) What is the target's speed just after the bullet emerges?

A 3.90 g bullet moving at 300 m/s enters and stops in an initially stationary 2.80 kg wooden block on a horizontal frictionless surface. What's the speed of the bullet/ block combination? What fraction of the bullet's kinetic energy was lost in this perfectly inelastic collision? How much work was done in stopping the bullet? If the bullet penetrated 5.00 cm into the wood, what was the average stopping force?
