Jack and Jill are maneuvering a 3300 kg boat near a dock. Initially the boat's position is < 2, 0, 3 > m and its speed is 1.1 m/s. As the boat moves to position < 4, 0, 2 > m, Jack exerts a force of < -410, 0, 205 > N, and Jill exerts a force of < 180, 0, 360 > N.
How much work does Jack do?
WJack = J
How much work does Jill do?
WJill = J
Which person exerted a force perpendicular to the displacement of the boat?
Jillboth Jack and Jill    neither Jack nor JillJack

What is the final speed of the boat?
vf = m/s

A metal cylinder with a mass of 1.20 kg is attached to a spring and is able to oscillate horizontally with negligible friction. The cylinder is pulled to a distance of 0.200 mfrom its equilibrium position, held in place with a force of 17.0 N, and then released from rest. It then oscillates in simple harmonic motion. (The cylinder oscillates along the x-axis, where x = 0 is the equilibrium position.) (a) What is the spring constant (in N/m)? _____...
