Question

Suppose a mass m is moving along a straight line with some initial velocity u.it is uniformally accelerated to velocity v, in the time t by the application of constant non-zero force F.the correct relation between F,v,u and t can be

Answer 1

The answer to this question is option (d).

We know that force is the rate of change of momentum of a body. This can be mathematically be expressed as:

F= mv-mu /t

 = m(v-u)/t

If we transpose t to the left hand side, we get

Ft = m(v-u)

so option (d) is the correct answer.
