A 0.5kg block made of Al is on a frictionless incline that makes a 60◦ angle with the horizontal. The entire system is on an elevator. In each case, determine whether the block will be sliding down the ramp, sliding up the ramp, or stationary. If moving, calculate its acceleration.

1. the elevator is at rest

2. the elevator is moving upward at constant velocity 2m/s

3. the elevator is moving upward at 2m/s and slowing down with an acceleration of 1.75m/s2 .

4. the elevator is at rest and is flooded with glycerol.

5. the elevator is at rest and is on the moon.

A.Your mass m=11 kg block slides down a frictionless ramp having angle theta=0.51 radians to the horizontal. After sliding down the ramp a distance L=16 m the block encounters a spring of spring constant k=551 N/m. The spring is parallel to the ramp. Use g=9.74 m/s/s for the acceleration of gravity. Calculate the maximum compression of the spring, in meters. Include labeled diagrams showing the initial and final configurations, and a discussion of the solution method based on energy conservation....
