Question

I need to figure how to do it and what equation to use for it

Answer 1

5.6 sec

Explanation:

Looking for:

Time

Given:

Speed = 55 m/s

Acceleration due to gravity = 9.8 m/s

Relationship:

`a=(\Delta v)/(\Delta t)`

We solve for t:

`\begin{gathered} \Delta t=(\Delta v)/(a) \\ \text{replacing} \\ \Delta t=(55)/(9.8) \\ t=5.6\text{ sec} \end{gathered}`

Solution:

5.6 sec
