Question

10. A force acts for 0.1 s on a body of mass 20 kg
initially at rest. The force is then withdrawn and
the body moves with a velocity of 2 ms. Find the
magnitude of force.
Ans. 40 N​

Answer 1

Answer:

Answer = 4 N

Explanation:

Time = 0.1 s,Mass = 20 kg,Velocity = 2 m/s

• Formula = F = Mass * Acceleration
• F = 20 * 2-0
• 0.1
• = 40
• 0.1
• Ans .= 4 N
