Question

A baseball is thrown straight up at 15m/s. How high will it go?

Answer 1

I am thinking if there's any use trying to explain it..

Answer 2

Do you have any ideas?

Answer 3

i do not know how to solve the problem... how do you solve it?

Answer 4

It is a physics problem/equation

Answer 5

try to do it by yourself: Where will have a zero speed?

Answer 6

at the start

Answer 7

But all of the equations need time, how do you know what the time is?

Answer 8

No sorry. at the start you are trying to throw it up. how would you have a zero speed at the beginning?

Answer 9

ooh so the beginning it is 15m/s and at the highest point it is zero?

Answer 10

actually. no tell me what is the equation of motion for such a problem?

Answer 11

DeltaX= VixT+.5xGxT^2

Answer 12

OK, but you need time of flying which can be easily obtained by this relation:
