A 0.25 kg lump of putty is thrown to the east at 7.0 m/s. The putty collides with a 1.5 kg block that is moving west at 0.5 m/s. The putty and block stick together after the collision.

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground
