Question

A body is projected horizontally from the top of a tower with a velocity of 30 m/s. The velocity of the body 4 seconds after projection is (g=10m/s²)

Answer 1

Answer:

70 m/s

Explanation:

Finding the final velocity use the formula v = u+at

Given:

v = ?

initial velocity (u) = 30 m/s

acceleration (a) = 10 m/s^2

time (t) = 4

Finding the final velocity use the formula v = u+at

= v = 30+(10*4)

= v = 30+40

= v = 70 m/s

Hence the final velocity is 70 m/s
