The particle starts from rest at t=0. What is the magnitude p of the momentum of the particle at time t? Assume that t>0. Express your answer in terms of any or all of m, F, and t.

The magnitude of the momentum of the particle after time, t is Ft = mv.

The given parameters:

The magnitude of the momentum of the particle after time, t is calculated as follows;

The force applied to the particle is calculated as;

Thus, the magnitude of the momentum of the particle after time, t is Ft = mv.

Ft

Explanation:

We are given that

Initial velocity=u=0

We have to find the magnitude of p of the momentum of the particle at time t.

Let mass of particle=m

Applied force=F

Acceleration,

Final velocity ,

Substitute the values

We know that

Momentum, p=mv

Using the formula

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

hey , the answer is c
