You are riding a 450-kg horse at 14.1 km/h east along a desert road. You have inertia equal to 60.0 kg. A police officer driving past (whom you know and who knows your inertia and the horse's inertia) measures your speed relative to the police car and calculates total kinetic energy of you and your horse to be 17.52 kJ.  What possible speed(s) could the police car have been driving at the instant the officer measured your speed? Express your answer in meters per second. If there is more than one answer, separate them by a c
