Question

8. An object (mass = 200 kg) is pushed up a friction- less inclined plane (0) by a force (F) that is parallel to the incline.

Answer 1

Answer #1

By work energy theorem

Wnet = UK

Wf+W, = (1/2)m(v² - u²)

(F×8)+(-5000) = (1/2)×200×(25² -15²)

8F -5000 = 40000

8F = 45000

F = 5625 N

(Note that work done by applied force is equal to force multiplied by displacement as both are in same direction.

$\Delta K$ is change in kinetic energy)
