Question

Philip is on a ride at Six Flags that launches him up into the air. If Philip is launched with a velocity of 20 m/s find the maximum height that Philip will reach. Use that g=10 m/s^2.

Answer 1

When Philip reaches the max high the speed would be 0

$\begin{gathered} vf^2=vo^2-2gd \\ 0=20^2-10\cdot2d \\ \frac{400}{2\cdot10}=d=20m \end{gathered}$
