An astronaut on a strange new planet having no atmosphere finds that she can jump up to a maximum height of 27 m when her initial l upward speed is 6.0 m/s.  What is the magnitude of the acceleration due to gravity on the planet?


To find the acceleration due to gravity on the planet, we can use the kinematic equation that relates initial velocity, maximum height, and acceleration:

\[
v^2 = u^2 + 2a s
\]

Where:
- \( v \) is the final velocity (0 m/s at the maximum height),
- \( u \) is the initial velocity (6.0 m/s),
- \( a \) is the acceleration due to gravity (negative because it opposes the motion),
- \( s \) is the maximum height (27 m).

We can rearrange this equation to solve for \( a \):

\[
0 = (6.0)^2 + 2 \cdot a \cdot (27)
\]

Now, let's solve for \( a \).

\[
0 = 36 + 54a
\]
\[
54a = -36
\]
\[
a = \frac{-36}{54} = -\frac{2}{3} \, \text{m/s}^2
\]

So, the magnitude of the acceleration due to gravity on the planet is:

\[
\boxed{0.67 \, \text{m/s}^2}
\]
