Question
ill has built herself an incline for a ball using a plank of wood that is one meter long. She sets he ball a he half-way pon friction is negligible see picture and practices rolling he ball up hill so hat he ball ust makes it to he op before olling all he way down. Let's let the op of the incline be he position x = 1.00 meters note he x-axis sho n Once she launches the bal it rolls freely she doesn't ouch it. and Pk the graoh that best represents an appropriate postion-tine graph for the ball 1) Pick the graph that best represents an appropriate position-time graph for the ball 2) Pick the graph that best represents an appropriate velocity-time graph for the ball. 3) Pick the graph that best represents an appropriate acceleration-time graph for the ball.Explanation / Answer
1) Position-time graph:
Correct answer: a)
2) velocity-time graph:
velocity decreases
Correct answer: a)
3)acceleration time graph:
acceleration is constant along negative direction
Correct answer: c)
