Acar starts from rest and accelerates uniformly to a speed of 72 km/hr over a distance of 500 m a further applied to bring the car to rest under unilorm deceleration in 5 seconds. find the distance travoled during braking acceleration raises the speed to 90 km/hr in 10 seconds. the brakes are now a)-50.5m b)-85.5m c)-625m d)- 45.5

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
