- Suppose a car travels 108 km at a speed of 30.0 m/s, and uses 1.80 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.30 x 108 ) per gallon.) (a) What is the force (in N) exerted to keep the car moving at constant speed? (Enter a number.) N (b) If the required force is directly proportional to speed, how many gallons will be used to drive 108 km at a speed of 28.0 m/s? (Enter a number.) | gallonsarrow_forward7. A crate of mass 10.0 kg is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100 N parallel to the incline, which makes an angle of 20.0° T with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 5.00 m. (a) How much work is done by the gravitational force on the crate? (b) Determine the increase in internal energy of the crate- incline system owing to friction. (c) How much work is done by the 100-N force on the crate?

- A hurricane wind blows across a 8m x 17m flat roof at a speed of 135 km/h. Calculate the force exerted on the roof. Hint: The thickness of the roof is small, so the change in potential energy between the inside of the house and the outside can be approximated to be zero. ρair =1. 28 kg/ m3 .arrow_forwardProblem 4: A 2.00 kg object moving in the x-y plane is under the influence of a force describe by the potential energy U (x,y) = (4.00 J/m³)x3 – (2.00 J/m4)y“.
