Final answer:
To find the mass of the boat with a kinetic energy of 15000 J and a speed of 5.0 m/s, we can use the formula for kinetic energy and solve for mass. The mass of the boat is approximately 600 kg.
Step-by-step explanation:
To determine the mass of the boat, we can use the formula for kinetic energy:
K.E. = 1/2 * mv²
Given that the kinetic energy is 15000 J and the speed of the boat is 5.0 m/s,
we can rearrange the formula to solve for mass:
15000 J = 1/2 * m * (5.0 m/s)²
Simplifying the equation, we find that the mass of the boat is approximately 600 kg.
