02) (35 points) A 10-kg bag B drops from a chute and lands on a 20-kg stationary cart A with a velocity of 2 m/s. The angle of the chute is known to be 0 = 40". Neglect rolling resistance of the cart and determine: a) (15 pts) the speed of the cart after the bag comes to rest on it, b) (15 pts) the impulse exerted by the ground on the cart A (Hint: assume a single reaction force between the ground and the cart), c) (5 pts) the average value of the ground reaction if the duration of the impact is 0.5 seconds.
