Question

a body of mass 10kg is moving with a velocity of 15m/s. When a force is applied on it, its velocity becomes 35m/s after 10sec. Calculate the applied force.​

Answer 1

Answer:

20 N

Explanation:

In this question :

Time = 10 sec

Initial velocity = 15 m/s

Final velocity = 35 m/s

Mass = 10 kg

acceleration = 35 - 15 / 10 (as a= v-u/t)

a = 2 m/s² [ '-’ indicate opposite direction ]

Now,

Force = m * a

Force = 10 *2

F = 20 N

Hope this helps..
