ANSWER:
5.6 sec
STEP-BY-STEP EXPLANATION:
Looking for:
Time
Given:
Speed = 55 m/s
Acceleration due to gravity = 9.8 m/s
Relationship:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
We solve for t:
[tex]\begin{gathered} \Delta t=\frac{\Delta v}{a} \\ \text{replacing} \\ \Delta t=\frac{55}{9.8} \\ t=5.6\text{ sec} \end{gathered}[/tex]
Solution:
5.6 sec
