A cart at the farmer's market is loaded with potatoes and pulled at constant speed up a ramp to the top of a hill. If the mass of the loaded cart is 5.0 kg and the top of the hill has a height of 0.55 m, then what is the potential energy of the loaded cart at the top of the hill? 273 1 0.13 J 25 J 130 J Question 5 (1 point) A race car brakes and skids to a stop on the road. Which statement best describes what happens? The race car does work on the road. The friction of the road does negative work on the race car. The race car and the road do equal work on each other. Neither does work on the other Oo oo N Question 14 (1 point) A shopper pushes a loaded grocery cart with a force of 15 N. The force makes an angle of 300 above the horizontal. Determine the work done on the cart by the shopper as he pushes the cart 14.2 m. A boy and a girl pull and push a crate along an ic horizontal surface, moving it 15 m at a constant speed. The boy exerts 50 N of force at an angle 520 above the horizontal, and the girl exerts a force of 50 N at an angle of 320 above the horizontal. Calculate the total work done by the boy and girl together 1663 2130 1700J 3 185J 1500J 4 225) 1098J Jestion 9 (1 point) 1000)
