A body of mass 5 kg 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.

Mass of the body = 5 kg
Initial velocity u = 10 m/s
Final velocity v = 35 m/s
Time t = 25 s
Acceleration a = \(\frac{v - u}{t}\)
= \(\frac{35 - 10}{25}\) = 1 m/s2
Force = m x a = 5 x 1
= 5 N
