Q. A 1650-kg car is traveling at 34.0 m/s. How fast must a 91.0-kg bicycle and rider be traveling to have the same kinetic energy as the car?

Q. A 58-kg student weighs himself by standing on a force scale mounted on a skateboard that is rolling down an incline. Assume there is no friction so that the force exerted by the incline on the skateboard is normal to the incline. What is the reading on the scale if θ = 30°?
