Q9. A 24-kg box was thrown onto a 35-kg cart with a speed of 7 m/s in the as shown. The cart was initially at rest. After the box lands on cart, it continues to move to the right at a speed of 2.9 m/s relative to the cart. If the launch occurs in 0.5 s, what is the average force the box exerts on the cart during the launch? Neglect the friction between the cart and the ground. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point, and proper SI unit. Your Answer: Answer units
