Amotor cycle is moving up an incline of 1 in 30 at a speed of 80 km/h, and then suddenly the engine shuts down. the tractive resistance of the motor is 5% of its weight. if no external force is applied and applying the law of conservation of energy, determine.
(i) the maximum distance it will travel before coming to rest
(ii)time the motor cycle will take to come to rest
(iii) deceleration of the motor cycle

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re,e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
