Question

Find initial velocity and time in air​

Answer 1

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

Step-by-step explanation:

Data

h = 30 m

vo = ?

dx = 300 m

Formula

t =
`\sqrt{(2h)/(g)}`

speed = distance / time

Process

`t = \sqrt{(2(30))/(9.81)} \\`

t= 2.47 s

speed = 300 / 2.47

speed = v = 121.46 m/s
