A 500 kg roller coaster starts from rest at the top of a 60-meter hill with a kinetic energy of 147,000 J. What is its speed?

A) 14.7 m/s
B) 24.4 m/s
C) 30.0 m/s
D) 40.2 m/s

Answer :

Final answer:

The speed of the roller coaster can be found using the formula for kinetic energy. The correct answer is 24.4 m/s.

Explanation:

To find the speed of the roller coaster, we need to use the formula for kinetic energy. The kinetic energy of the roller coaster is equal to its mass multiplied by its speed squared, divided by 2. By rearranging the formula and substituting the given values, we can solve for the speed. The correct answer is option B) 24.4 m/s.
