What is the kinetic energy of a car that is traveling at 17.3 m/s if it has a mass of 1,345 kg? Submit your answer in exponential form

The rate of energy use in a typical house is about 2 kW. If the kinetic energy of a car (mass 1358 kg) is equal to the total energy used by the house in 1 min, what is the car's speed? m/s

You are throwing a ball to a friend while taking physics and begin to wonder about work. You know that when you throw, you exert a force of 655 N on the ball (which has mass 1.84 kg), and that you do so for a distance of 0.27 m. If you start the throw from rest, what is the final speed of the ball? When you show your work for this question, you must do the calculations using work and energy for credit. If you use kinematics you will not recieve credit. Your Answer: units Answer

A 2 kg object is thrown downward on an incline with initial velocity of 5m/s. After 12 meter displacement, its velocity becomes 8m/s. What is work done on the object by friction during the motion? (friction is between object and inclined surface). (Please type all steps of your solution and show the formulas you have used.)
