Give it a push!!
A body of mass 5 kg is moving with a velocity of 10 m/s. A force is applied so that in 25 seconds, It attains a velocity of 36 m/s. Calculate thhe value of the force applied (In newtons)
Enter your answer as a number upto 1 decimal place
Though this should at least have been a level 2 problem, It is not so bebcause I am Level 1 in Mechanics.
The answer is 5.2.

Mass of body(m) = 5 kg
initial velocity(u) = 10 m/s
final velocity(v) = 36 m/s
time(t) = 25 s
acceleration = (v-u)/t = (36 - 10)/25 = 26/25 m/s2
force = ma =5*26/25 = 5.2 newton
