Question

a ball thrown vertically upward with speed of 9.6 metre per second from the top of a tower return to the earth in 6 seconds find the heiht of Tower​

Answer 1

initial velocity, u = 9.6m/s

final velocity, v = 0 m/s

Time taken, t = 6 s

Acceleration due to gravity, a = -9.8 m/s^2

using second equation of motion,

distance (s) = ut+1/2gt^2

s = 9.6*6 + 1/2 *9.8*(6)^2

s = 234 m

Height of tower is 234 m
