1.	A body of mass 5kg is moving with a velocity of 10 m/s. A force is applied to it so that in 25 seconds, it attains a velocity of 35 m/s. Calculate the value of the force applied.
Answer» Mass of the body = 5kg Initial velocity, u = 10 m/s Final velocity, v = 35 m/s Time, t = 25s Acceleration, a = (v-u)/t = 1 m/s² Force = ma = 5N

A body of mass 5kg is moving with a velocity of 10 m/s. A force is applied to it so that in 25 seconds, it attains a velocity of 35 m/s. Calculate the value of the force applied.

Answer»

Mass of the body = 5kg

Initial velocity, u = 10 m/s

Final velocity, v = 35 m/s

Time, t = 25s

Acceleration, a = (v-u)/t = 1 m/s²

Force = ma = 5N
