Question

an object of mass 5kg is moving with a velocity of 10m/s . A force is applied so that in 15 s, it attains a velocity of 25 /m/s . what is the force applied on the object?​

Answer 1

Answer

5 N

Explanation

Mass, M=5 kg, Initial Velocity, V=10 m/s, Final Velocity, V=25 m/s

Time under which it attains new speed, T= 25s

Acceleration, A= (V-U)/T

                         =(25-10)/15

                         =(15)/15

                         = 1 m/s²

Force, F = M×A

              = 5×1

              = 5 N
