Question

Ball is thrown vertically upward with a speed of 19.6 m/s from top of a tower returns to earth in 6 sec find height of tower

Answer 1

Answer:

h = 196

Explanation:

S = Vi + 1/2 at2

here S= h

vi = 19.6

vf = 0

t = 6

acceleration due to gravity = 9.8

h = 19.6 + 1/2 (9.8)(6)2

h = 19.6 + 176.4

h = 196
