Aplane drops a hamper of medical supplies from a height of 3250 m during a practice run over the ocean. the plane’s horizontal velocity was 129 m/s at the instant the hamper was dropped. what is the magnitude of the overall velocity of the hamper at the instant it strikes the surface of the ocean? the acceleration of gravity is 9.8 m/s 2 . answer in units of m/s.

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
