Question

Certain force acting on a 20 kg mass changes its velocity fron
5 m s-1 to 2 m s-l. Calculate the work done by the force کام​

Answer 1

Given : Initial volume = u = 5 ms -¹

Final velocity = v = 2 ms-¹

From work-energy theorem,

W=ΔK.E

W = 1/2 mv²- 1/2 mu²

W = 1/2 x 20 x 2² - 1/2 x 20 x 5²

⟹W=−210 J
