4.) A cart with mass m = 1:2 kg touches a block with mass M = 7:3 kg.
Both blocks sit on a horizontal surface; the wheel of the cart eliminates
the friction with the surface; the coecient of kinetic friction between
the block M and the surface is not known. The box and cart are initially
at rest.
a) We exert a horizontal push P = 63:3N and move the block-cart
system through the distance s = 0:87 m. The cart and box move at the
speed 2.4 m/s at the end of the push. What is the work done by us?
b) Find the forces acting on the cart and the work done by these forces!
c) Find the forces acting on the block and the work done by these forces!

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.500 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...
