An automobile with a mass of 1020.00 kg has 3.96 m between the front and rear axles. Its center of gravity is located 0.409 m behind the front axle. With the automobile on level ground, determine the magnitude of the force from the ground on: a. each front wheel (assuming equal forces on the front wheels)
b. each rear wheel (assuming equal forces on the rear wheels).

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa. (0.757, 4.37 kw, 5.12, 6.18, 3.91 kw)

In this lab you will use a cart and track to explore various aspects of motion. you will measure and record the time it takes the cart to travel certain distances, and then complete some calculations. in the space below, write a scientific question that you will answer by doing this experiment.
