The Grinch is trying to push a 5000-kg sled up the side of Mount Crumpit (whose side make an angle of 60 degrees above the horizontal) when he suddenly loses his grip and lets go of the sled. The sled starts sliding back down and soon afterwards hits a tree with an impact speed of 60 m/s, three hundred meters further down the slope.

Find the amount of gravitational potential energy that has been lost during the slide (in J).

How much kinetic energy has the sled gained during the slide?

The force responsible for the overall loss of mechanical energy is

A. normal force
B. weight
C. static friction
D. kinetic friction

The missing mechanical energy has been

A. lost for good
B. turned to kinetic energy
C. turned to potential energy
D. turned to thermal energy

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
