Question

A net force of 100 newton's is applied to a wagon for 5 seconds. This causes the wagon to undergo a change in momentum of..

Answer 1

\[Ft=mv-mu=100\times5=500Ns\]

Answer 2

Change in momentum is impulse
Impulse=force x time
Impulse =100 x 5
impulse=500
Your final answer is \[500Ns= 500\frac{ kg \times m }{ s^2}s= 500\frac{ kg \times m }{ s }\]
