## Homework Statement

Ok i am working through some course work questions and have been asked to calculate the change of momentum of the 200kg crate. I have the following information after working through the previous questions

Mass of crate = 200Kg

Distance moved (horizontally) = 20m

time = 4.07s

Initial Velocity = 0 m/s

Final velocity = 9.82 m/s

Aceleration = 2.41 m/s/s

I realize i don't need all this information but wanted to include all the information i have gained about the system. I have also attached my initial free body diagram.

## Homework Equations

Impulse = ft = mΔv

## The Attempt at a Solution

So this is where I'm having difficulties i think i have got confused with all the information i have already gained about the system but my attempt is as below would appreciate any pointers in the right direction.

Ft = mΔv

F = mΔv/t

F = (200Kg x 9.82m/s)/4.07s

F = 482.56N
