Homework Statement


When throwing a ball, a student has a friend time how long it takes the ball to reach the maximum height. Before they start the experiment, the friend predicts: “If you throw the ball faster, the ball will reach the highest point in less time.”
Do you agree or disagree with this statement? Why or why not?

If you disagree, how would you correct it?

2. No equations necessary

The Attempt at a Solution


I predicted that it would not reach the highest point in less time because gravity would be the only force acting on the ball once the ball leaves his hand. Help??

Do you think if you threw it fast enough, then it wouldn't come down at all?

Obviously I do not believe that if you look at my predicted answer.

Why is gravity being the only force important? I don't see any logic in your answer.

What is the relationship between initial speed and time to reach the highest point?

His question is important. You stated in your OP that no equations are necessary. I suggest that you should indeed use equations to figure this one out. What is the equation for the time to maximum height based on initial vertical velocity?
