Answer:
490.5 m
Explanation:
we can use the formula s = ut + ½at^2
s= displacement (height of tower)
initial velocity u = 0 m/s
acceleration a = take 9.81 ms-2 (acceleration due to gravity, which is a constant. depending on the given instructions of the question, it may not be exactly 9.81. Some take 10, some take 9.80665)
time t =10s
s = 0t + 1/2 (9.81)(10)^2
s = 490.5 m
