Question

A4 kg object possesses 18 J of kinetic energy. What is its velocity?

Answer 1

Answer:

velocity = 3 m/s

Explanation:

kinetic energy = 1/2 * mass(kg) * velocity²

Using the formula:

                                     18 = 1/2 * 4 * velocity²

                                      9 = velocity²

                                     velocity = 3 m/s
