Compute each part of given question:

Question: A .22 rifle bullet, traveling at 350 m/s, strikes a block of soft wood, which it penetrates to a depth of 0.130m. The block of wood is clamped in place and doesn't move. The mass of the bullet is 1.80 grams. Assume a constant retarding force.

Part A: How much time is required for the bullet to stop?

Part B: What force, in Newtons, does the wood exert on the bullet?

I need help to find how much time is required for the bullet to stop.
