a block with mass m = 2.00 kg slides without friction on a ramp inclinced at 53.1 degrees above horizontal. A spring with constant k = 156.75 N/m is released from rest 4.0 m above the equilibrium placement of the spring. What is the lowest distance along the ramp that the block will reach? How much is the spring compressed when the block is placed on it at rest?
The Moon moves noticeably on the celestial sphere over the space of a single night. To show this, calculate how long it takes the Moon to move through an angle equal to its own angular diameter (0.5 degrees) against the background of the stars. Gi..
