Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. assume free fall.
part a :

if the faster stone takes 8.00 s to return to the ground, how long will it take the slower
stone to return? t= ?

part b :

if the slower stone reaches a maximum height of h, how high (in terms of h) will the faster stone go?

Amplitude is a measure of a waves a; speed b; distance c; energy d; frequency
