Question

6.4kJ of energy causes a displacement of 64m in a body in the direction of force in 2.5s.Calculate
1.The force applied.
2.Power in HP.
Take 1 HP = 746W

Answer 1

Hint: \[W= \vec F \vec d\]

Answer 2

Where W = work, F = force, d = displacement

Answer 3

Also, \[P = \frac{ W }{ t }\] where P = power, W = work, and t = time

Answer 4

100N and 3.43 HP

Answer 5

yup
