Question

Find initial velocity and time in air​

Answer 1

Answer:

The answer to your question is: v = 121.46 m/s

Explanation:

Data

h = 30 m

vo = ?

dx = 300 m

Formula

t = $\sqrt{\frac{2h}{g}}$

speed = distance / time

Process

$t = \sqrt{\frac{2(30)}{9.81}}$

t= 2.47 s

speed = 300 / 2.47

speed = v = 121.46 m/s
