Naveen claims that linear momentum is conserved in this simulation. (Ignore rotational momentum effects) A) Using data from the test A for Ball 1 or Ball 2, calculate the ball's momentum before and after the collision. The formula for momentum is p=mv.

Naveen claims that no net force is on the system, meaning that the momentum is conserved over time.

B) Using data from test B, verify Naveen's claim with evidence and calculations.

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?
