Question

A rocket is fired upwards with an intial velocity of 46.5 m/s. find the rocket's maximum height

Answer 1

The value is
`s = 110.32 \ m`

Step-by-step explanation:

From the question we are told that

The initial velocity is u= 46.5 m/s

Generally from kinematic equations we have that

`v^2 = u^2 + 2as`

Here
`a = -g = -9.8 \ m/s^2`

The negative sign is because it is moving against gravity

At maximum height v = 0 m/s

So

`0 = (46.5)^2 + 2* (-9.8)s`

=>
`s = 110.32 \ m`
