6 / 6 - 100% + 19. (eight marks) Sanjay is working on the following physics problem: A 200 kg boat is travelling at 10 m/s [N] when it experiences a strong current 10 m/s [E]. What is the total kinetic energy of the boat and how much work does the current do? He comes up with the following solution: "Since the current accelerates the boat until it reaches 10 m/s [E], (200 kg ) (10 m/s) the work done by the current is 2 = 10 kJ and since the boat still has a velocity heading 200 kg ) (10 m/s) (200 kg) (10 m/s)? north, the total kinetic energy must be 2 - 2 = 20 kJ. Is Sanjay correct? If so, explain. If not, what mistake did he make?
