Q. A 5.25-kg ball of clay is thrown downward from a height of 2.79 m with a speed of 4.41 m/s onto a spring with k=1530 N/m. The clay compresses the spring a certain maximum amount before momentarily stopping.
a)Find the maximum compression of the spring.
b)Find the total work done on the clay during the spring's compression.
