It falls behind the cart 3. It falls in front of the cart It falls right back into the cart It remains at rest 4. 5.

Answer 1

Option - 4 The ball falls right back into the cart

Explanation:- The track is inclined therefore the cart accelerates. However, the ball has the same component of acceleration along the track as the card does. This is essentially the component of g acting parallel to the inclined track. So the ball is effectively accelerating down the incline, just as the cart is, and it falls back into the cart.
