Question

Please provide claer explanations

Thanks a lot !

1.4: Imagine that the only energy losses in driving your car come from air resistance (i.e., no losses due to braking or inefficiency). If the car masses 1.50 metric tons (1500 kg) and normally produces 125 horse- power 932×10° W then far could the car drive on 10 gallons of gasoline where each gallon contains 1.3 x 109 J of enersy? Assume that the air resistance force on the car is 1000. N. (10 points) Imagine two uniform-density objects (pinning at the same rate on the space station: (1)A sphere and (2) acylinder s has more kinetic energy, and why? How much more kinetic energy does your choice have than its rival? (10 points) pinning around its axis of symmetry. Both have identical mass. Whick
