Two blocks of clay, one of mass 1.00 kg and one of mass 3.00 kg, undergo a completely inelastic collision. Before the collision one of the blocks is at rest and the other block is moving with kinetic energy 32.0 J. If the 3.00 kg block is initially at rest and the 1.00 kg block is moving, what is the initial speed of the 1.00 kg block?

The initial speed of the 1kg block is 8 m/s.

Explanation:

The question simply asks for the initial speed of the 1.00 kg block.

The initial kinetic energy of the 1kg block is = 32 Joules

Using this kinetic energy, and the equation below, we can find the speed of the 1kg block:

Kinetic Energy =

v = 8 m/s

The initial speed of the 1kg block is 8 m/s.

i think the answer would be reserve.
