Question

when a body of 10kg mass is moving with 100m/s. what is the force required to stop the body in seconds

Answer 1

Answer:

similar

Explanation:

Time = 3 sec.

Initial velocity = 15 m/s

Final velocity = 0 m/s [ stop ]

Mass = 10 kg

First find “acceleration” = 0 - 15 / 3

a = -5 m/s² [ '-’ indicate opposite direction ]

Now,

Force = m * a

Force = 10 * - 5

F = - 50 N
