Question

A stone is dropped from the top of a tower takes 5 seconds to reach the
ground Calculate the height of the toner (take g = 10ms​

Answer 1

Answer:

A = 10m/s

U = 0

T = 5

S = UT + 1/2 at2

S = 0*5 + 1/2 * 10 *5 *5

S = 125 m

Answer 2

a=g=10m/s² (given)

t=4s

u=0m/s (initial velocity at rest)

So, height= ut+1/2at²

=(0) (u) + 1/2(10)(16)

=80m

So,height of the tower= 80m.

Hope this helps.
