On the planet Sulvania, a mountain with an elevation of 1310 feet is the highest peak on the east coast of a land mass. The summit of the mountain is the first place on the land mass to be lit by the rays of the sun. How much sooner do the first rays of the sun touch the summit than the base of the mountain below, at sea level? Assume that one rotation of Sulvania takes 24 hours and that the radius of Sulvania is 2720 miles.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
