Question

constant force FA is applied to an object of mass M, initially at rest. The object moves in the horizontal x-direction, and the force is applied in the same direction. After the force has been applied, the object has a speed of vf. Which mathematical routines can be used to determine the time in which the force is applied to the object of mass M

Answer 1

Δt=ΔpxFA

Δt=MvfFA

Step-by-step explanation:

Answer 2

Step-by-step explanation:

When a force is applied for time t , it creates impulse . The impulse creates change in momentum .

In the change in momentum = Mvf - 0 = Mvf .

Impulse = FA x t , t is time .

FA x t = Mvf

t = M x vf / FA .
