Question

A body falls from the top of a tower and strikes the ground with a velocity of 80 m/s. Find the height of the tower

Answer 1

Answer:

Explanation:

as per newtons law V²-  U² = 2 a s

v is the final velocity

u is initial velocity

a is accelaration

s is displacement

here assuming initial velocity to be zero

6400/2g = S  ( g = a ) acclearation due to gravity

= 320 m
