A block initially at rest explodes into two pieces E and D, which slide on a floor in a stretch without friction and then enters regions with friction, where they end up stopping. Piece E, with a mass of 2.0 kg, has a coefficient of kinetic friction uE = 0,40 and comes to rest after traveling a distance de = 0,15 M. Piece D encounters a coefficient of kinetic friction un=0,50 and comes to rest after traveling a distance d, = 0,25 m. What was the mass of the block?

In the figure, block 1 of mass mi slides from rest along a frictionless ramp from height h = 2.7 m and then collides with stationary block 2, which has mass m2 = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction k is 0.55 and comes to a stop in distance d within that region. What is the value of distanced if the collision is (a) elastic and (b) completely inelastic?

A bullet of mass 0.0366kg and an initial speed of 353m/s is fired through a block of material with a thickness of 0.435m.
