Question

Physics/Calculus help please. I've attempted something

Answer 1

Is it wrong to assume that H= V sound times T hear?

Answer 2

since velocity times time will give you distance traveled.

Answer 3

You also have to include the time it takes the ball to reach the bottom.

Answer 4

The questions wants me to solve for H right?

Answer 5

The time taken to hit the bottom is\[t_1 = \sqrt{\frac{2H}{g}}\]The time taken for the sound to reach the top is\[t_2 = \frac{H}{v_s}\]The sum of these two times is total time \(T\)

Answer 6

how did you get t1?

Answer 7

and what do we need the total time for?

Answer 8

Well, use\[s = ut + \frac{1}2at^2\]

Answer 9

what is that?

Answer 10

Wouldn't the acceleration be negative
