If you drop a basketball off a cliff and it travels at an average speed of 15 m/s, if the cliff is 60
meters high, how long will it take before the basketball hits the ground?
Remember that
The speed (s) is equal to divide the distance (d) by the time (t)
so
s=d/t
Solve for t
t=d/s
substitute teh given values
t=60/15
t=4 sec
therefore
the answer is 4 seconds
