Aparticle travels along a straight line with a velocity v = (12 – 3t2) m/s. when t = 1 s, the particle is located 10 m to the left of the origin. determine the displacement from t = 0 to t = 10 s, and the distance the particle travels during this time period.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
