NEET Physics Question - Work Energy and Power - Principal of Conservation of Energy

Rankers Physics

Topic: Work Energy and Power

Subtopic: Principal of Conservation of Energy

A body is released from position A as shown in figure. The speed of body at position B is Image related to

10 m/s

10√2 m/s

20 m/s

20√2 m/s

From Principal of Conservation of Energy

Ui + Ki= Uf+ Kf

⇒ mg(50) + 0 = mg(10) + ½ m v²

⇒ v² = 800

⇒ v = 20√2 m/s
