Question

(a) A block of 2.0 kg travels at 3.0 m/s for 0.50 m along a smooth, horizontal surface before it hits a relaxed spring. The block is slowed to zero velocity when the spring is compressed by 0.15 m. What is the spring constant of the spring?

(b) A block of 2.0 kg is dropped from rest. It falls a vertical distance of 0.50 m before it hits the same spring as in part (a), but it is relaxed vertically. How far does the block compress the spring before momentarily coming to rest?

(c) A mass of 2.0 kg is released from the top of a smooth (frictionless) incline which
makes an angle of 41 with respect to the horizontal. It travels a distance of 0.50 m
before hits the same spring that is now relaxed along the incline. How far does the
block compress the spring before momentarily coming to rest?

Explanation / Answer

(a1) 1/2 kx^2 = 1/2 M v^2

K= 800 N/m
