A body is released from position A as shown in figure. The speed of body at position B is
Short Solution (Best for NEET):
To solve this problem, we apply the core principles of Principal of Conservation of Energy. Understanding the underlying formula is key to arriving at the correct answer below:
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
