Question

How fast would a ball have to be thrown upward to reach a maximum height of 100 ft?

Answer 1

Is this a math problem or physics?

Answer 2

Depends how heavy the ball is. Post this in the physics forum >.>

Answer 3

^it doesn't depend on how heavy it is.

Answer 4

=.= then i misread it, "how fast" .. ;~;

Answer 5

its a math problem

Answer 6

thank you

Answer 7

^do you understand it?

Answer 8

yes

Answer 9

Then explain it to me :) this will help you understand it completely.

Answer 10

I'm assuming this is an algebra problem.

The initial speed is equal to the speed the ball would reach if dropped from 100 feet.

Use the equation 16t2 − v0t + h = 0
