Answer:
height of tower= 78.48 meters
Explanation:
So here are your givens:
time(t)= 4 s.
initial velocity(u) = 0 m/s
acceleration due to gravity (g)= 9.81 m/s^2
distance(s)=s meters
using one of Newton's equation of motion ;
[tex]s=ut+\frac{1}{2} gt^{2} \\s=0(4)+\frac{1}{2}(9.81)(4)^{2} \\s=\frac{1}{2} (9.81)(16)\\s=\frac{156.96}{2} \\s=78.48[/tex]
height of the tower from the ground=total distance covered by bearing
height of tower= 78.48 meters
