A 24.0g bullet is fired horizontally, embedding itself in a 10.0kg block initially at rest on a horizontal ice surface. The block (with the bullet embedded) slides along the ice, coming to rest in 2.00s at a distance of 60.0cm from its original position. Assume that the frictional force stopping the block is constant.

a) Calculate the initial velocity of the bullet-block combination.

b) Calculate the initial velocity of the bullet.

c) Is this an elastic or inelastic collision? How do you know?

A 10 g bullet is fired with 450 m/s into a 10 kg block that sits at rest on a wooden table 20 cm from the edge of the table. The bullet gets embedded in the block (perfectly inelastic collision). The block, with the embedded bullet, then slides to the edge of the table and drops down with some initial velocity while leaving the edge of the table. The coefficient of kinetic friction between the block and the surface of...

A 92.0 g wooden block is initially at rest on a rough horizontal surface when a 11.0 g bullet is fired horizontally into (but does not go through) it. After the impact, the block–bullet combination slides 6.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.750, determine the speed of the bullet (in m/s) immediately before impact.
