Answer to Question #337081 in Physics for Mark

Question

What is the momentum of a vehicle if a force of 1000 N is applied on it in 0.50 seconds if it started from rest?

Answer 1

The Newton's second law says

$$\Delta p=F\Delta t$$

Hence, the final momentum

$$p_f=p_i+F\Delta t\\ =0+1000*0.5=500\:\rm kg\cdot m/s$$
