The horizontal force exerted between the tires of a 500kg car and the ground is 980N. if the car starts from rest, how far will it go in 5 seconds?

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
