Luke Autbeloe drops an approximately 5.0 kg box of shingles (weight = 50.0 N) off the roof of his
house into the swimming pool below. Upon encountering the pool, the box encounters a 50.0N

Answer:
CORRECT ANSWER IS B
Explanation:
The box first accelerates with a negative (downward) acceleration until it hits the water. Upon hitting the water, the box experiences a balance of forces (50 N downwards due to gravity and 50 N upwards due to the water). Thus, the box will finish its motion moving with a constant velocity. Graph B depicts both the initial negative acceleration and the final constant velocity.
