## Homework Statement

m = 50kg

Distance covered = 100m

T = 3.22

Solve for average momentum.

## Homework Equations

X = 1/2 at^2

p = mass*acc*change time

## The Attempt at a Solution

100 = 1/2 a (3.22)^2

a = 200/10.3684 = 19.28937m/s^2

f = 50 * 19.28937 = 964.4689

change momentum = 964.4689 * 3.22 = 3105.59 kg m/s

The answer is half of this, why exactly is it half?
