An object is dropped from a height H above the ground. This free-falling object requires 0.904 s to travel the last 34 m before hitting the ground.
From what height H above the ground did
the object fall? The acceleration of gravity is 9.8 m/s^2.
Answer in units of m
i understand that t= .904s
distance is 34m
and a = 9.8m/s^2
But I'm not sure what else to do here?
