Answer: A 3600 kg boat is moving with a speed of 2.4 m/s. A much smaller 100 kg jet ski has the same amount of kinetic energy. The is the speed of the jet ski is 14.4 m/s².

Explanation: To find the correct answer to the question given, we need to know more about the Kinetic energy.

What is kinetic energy?

  • It is the form of mechanical energy possessed by a body by virtue of its motion.
  • The expression for kinetic energy of a body of mass m having velocity v can be written as,

                        [tex]KE=\frac{1}{2} mv^2[/tex]

How to solve the problem?

  • Given that the kinetic energy of both the boat and the jet are equal.
  • Let, mass and velocity of the boat will be m1 and v1 and mass and velocity of the jet will be m2 and v2, then,

                        [tex]\frac{1}{2}m_1v_1^{2} =\frac{1}{2}m_2v_2^2\\ Thus, \\v_2^2=\frac{m_1v_1^{2}}{m_2} =207.36\\v_2^2=14.4 m/s^2[/tex]

Thus, we can conclude that, the is the speed of the jet ski is 14.4 m/s².
