Question

A rock falls from rest a vertical distance of 0.72 meter to the surface of a planet in 0.63 seconds.  The magnitude of the acceleration due to gravity on the planet is

anonymous · Answer

This involves the kinematic equations in the vertical direction. Find which equation to use and plug in your values and solve for acceleration.

theeric · Answer

Also, draw a picture if the problem doesn't make sense right away!

theeric · Answer

The equation you choose (or find) has to have acceleration, and can distance, initial velocity, and time.

theeric · Answer

That's because you are looking for the acceleration and you have those other pieces of information. Initial velocity is the tricky one to find. If you don't see it, try asking in this post or another! Good luck!
