**A 500 newton ballerina did 250 joules of work to lift herself upward through the air. She landed a total of 2.5 meters to the left after completing her jump. How high did she jump?**

**Answer:**

As she did 250 J of work, the maximum height reached by her in the jump is equal to 250/500 = 0.5 m.Work is equal to the product of force and displacement. Once the ballerina has reached the maximum height, she is pulled down due to the force of gravity.
