Explanation:
Detailed explanation-1: -It fires a ball straight out of the cannon as it moves. After it is fired, what happens to the ball? Because the track is inclined, the cart accelerates. However, the ball has the same component of acceleration along the track as the cart does!
Detailed explanation-2: -b. Yes. The answer changes if the cart is accelerating.
Detailed explanation-3: -There are two ways to find the acceleration of the cart. First, we can calculate the value of the acceleration using forces and Newton ‘s Second Law. However, we can also use the kinematics equations to find the acceleration, if we can measure certain quantities.
