Question

A body is throw horizontally with velocity 4m/s from a height of 80m. Find the velocity with which it hits the ground

Answer 1

initial velocity = 4 m/s

final velocity =0 (because it hits the ground it comes to rest)

distance =80 m

v²-u²=2as

0²-4²=2×a×80

-16=160 a

-16/160=a

-1/10=a
