# Planet X Gravity

Pro Problems > Physics > Energy and Work > Work## Planet X Gravity

On Planet X, a car does 405,000 J of work increasing its speed from 15 m/s to 30 m/s on a horizontal surface. It then does 96,000 J of work driving up a 25 meter hill at a constant speed. If an object is dropped from a height of 1000 meters on Planet X, how fast will it be traveling when it reaches the ground? Assume no air resistance on Planet X.

## Solution

In order to make it feasible for teachers to use these problems in their classwork, no solutions are publicly visible, so students cannot simply look up the answers. If you would like to view the solutions to these problems, you must have a Virtual Classroom subscription.## Similar Problems

### Blasting off from Planet X

An astronaut is in a lander, which is taking off from Planet X. The lander's thrusters do 12,288,000 Joules of work lifting the lander (at a constant speed) to a height of 1000 meters.

If the astronaut had bailed out first, the lander could have risen to a height of 1024 meters doing that same amount of work.

If the lander, with astronaut on board) had done the same amount of work accelerating horizontally, it would have reached a speed of 40What is the acceleration due to gravity on Planet X?

### Top of the Hill

### Lift the Box
