Question

#14You jump off a diving platform that is 20 feet off the ground with an initial upward velocity of S feet persecond. How long will it take for you to hit the water?

Answer 1

Hello!

First, let's imagine this situation below:

We can solve it using the formula of the velocity, look:

`\begin{gathered} \boxed{v=(\Delta s)/(\Delta t)} \\ \\ 5=(20-0)/(\Delta t)\rightarrow(5)/(1)=(20)/(\Delta t)\rightarrow5\Delta t=20 \\ \\ \Delta t=(20)/(5) \\ \\ \Delta t=5\text{ seconds} \end{gathered}`

Answer:

5 seconds.
