Joint and Combined Variation

Question 5 of 10 • EAP-Algebra Functions and Data Analysis B

The kinetic energy, K, of an object varies jointly with the mass of the object and the square of the velocity of the object. A 50-kg object moving at a velocity of 20 meters per second has 10,000 joules of kinetic energy. How many joules of kinetic energy does a 25-kg object moving at a velocity of 10 meters per second have?

Answer

250 joules

1,250 joules

2,500 joules

3,125 joules
