Question

A 0.03-1b bullet traveling at 1300 ft/s strikes the 10.8-lb
wooden block and exits the other side at 50 ft/s as
shown. The coefficient of kinetic friction between the block
and the surface is μ = 0.5. (Figure 1)

Expert Solution

Step 1

Given that:

Initial velocity of the bullet is 1300 ft/s

Final velocity of the bullet is 50 ft/s

(a) It is required to determine the speed of the wooden block just after the bullet exits the block.

(b) If coefficient of kinetic friction between the block and the surface is 0.5, then it is required to determine the distance the block will travel before it stops.
