Question

If the kinetic energy of a 5.5 kg bowling ball is 15.6 Joules, calculate its velocity.

Answer 1

We are given –

• Mass of bowling ball is = 5.5 kg
• Kinetic Energy is = 15.6 J
• Velocity =?

As we know –

↠K.E = 1/2 mv ²

↠ 15.6 = 1/2 × 5.5 × v ²

↠15.6 = 2.75 v ²

↠2.75v ² =15.6

↠v ² = 5.67

↠v=√5.67

↠v = 2.381 m/s

• Henceforth,velocity is 2.38 m/s
