Reference no: EM13528966

Jack and Jill are maneuvering a 3400 kg boat near a dock. Initially the boat's position is < 2, 0, 3 > m and its speed is 1.0 m/s. As the boat moves to position < 4, 0, 2 > m, Jack exerts a force of < -400, 0, 200 > N, and Jill exerts a force of < 160, 0, 320 > N.

How much work does Jack do?

WJack = J

How much work does Jill do?

WJill = J

neither Jack nor Jill

Jill

both Jack and Jill

Jack

What is the final speed of the boat?
