According to Newton's First Law of Motion . every action has an equal and opposite reaction
objects in motion will keep moving unless acted upon by force
objects at rest can start moving on their own
objects in motion stop moving once force is removed

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.
