A bullet with a mass of 5.0g is fired horizontally into a 2.0 kg wooden block that is at rest on a horizontal surface. The oefficient of kinetic friction between the block and the surface is u = 0.20. After the bullet strikes the block, the block lides along the surface. It comes to rest after it slides 2.0 m. Vhat was the initial speed of the bullet?

Question
A bullet with a mass of 5.0g is fired horizontally into a 2.0 kg wooden block that is at rest on a horizontal surface. The
coefficient of kinetic friction between the block and the surface is u = 0.20. After the bullet strikes the block, the block
slides along the surface. It comes to rest after it slides 2.0 m.
What was the initial speed of the bullet?
