-One 2 kg lump of clay traveling at 33 m/s overtakes a second 1 kg lump traveling at 5.3 m/s. After collision they are stuck together. To the nearest tenth of a m/s what is their common velocity? -If the second lump in the above problem was moving to the left before the collision what would be the answer?

A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...

A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M=1.33 kg that is hanging on a light inextensible string of length L=0.767. The bullet becomes embedded in the block, which was originally at rest. What is the smallest value of vv which would cause the block-on-a-string to swing around and execute a complete vertical circle?
