Q.8. A block of mass m = kg is placed against a spring of spring constant k = 1960 N/m on a frictionless inclined plane with an angle 0 = 30° to the hori- %3D zontal, at the equilibrium position O of the spring. The block is pushed against the spring compressing it a distance x to point A, x 0A then released from rest. If the compression of the spring is x = 20 cm then the difference in gravitational %3D potential energy of the block between point A and point B (highest point) is:

k :
= 1960 N/m on a frictionless inclined plane with an angle 0
= 30° to the hori-
zontal, at the equilibrium position O of the spring. The block is pushed against the
spring compressing it a distance x to point A, x OA then released from rest.
If the compression of the spring is x = 20 cm then the difference in gravitational
potential energy of the block between point A and point B (highest point) is:
a. AP. E, = 9.8J
