Answer:
Physics the fourth
A B
What impulse occurs when an average force of 10 N is exerted on a cart for 2.5 s? 10 N x 2.5 s= 25 Nxs
What change in momentum did the cart undergo? 25 kg x m/s
If the mass of the cart is 2 kg and the cart is initially at rest, calculate it's final speed. 12.5 m/s
So in other words: 4.0 m/s2
