Question

A body of mass m is initially moving with a velocity u.When a force F acts on the body it picks up velocity v in t second so that the acceleration a is produced. Using this data derive the relation between the force, mass and acceleration.

Answer 1

Answer:

F=ma

Explanation:

According to Newton's second law of motion,

F proportional to rate of change of linear momentum,

F proportional to mv-mu/t

F=k(mv-mu/t)

k= 1,

F=m(v-u/t)

Acceleration is rate of change of velocity,

v-u/t=a

F=ma

F/m=a

F/a=m
