Question

a projectile was fired with the horizontal velocity of 300m/s from the top od a cliff 100 m highhow long will it take to reach the ground​

Answer 1

Answer:

4.472s

Explanation:

since it was fired with a horizontal velocity = 300 m/s

The vertical initial velocity was zero = 0 m/s

y= 0.5 gt²

100 = 0.5 X 10 X t²

t² = 20 t= 2√5 s

t= 4.472s

t = 2√5 s = 2 x
