a hill and has an initial speed of 118 km/h at the bottom of the hill....
A car has an initial speed of 118 km/h and climbs up an incline with its engine DISENGAGED (no engine force). DON"T use scientific notation. Angle is 33 degrees. (a) If work done by friction is negligible, How high (the h in the figure) a hill can the car coast up (engine disengaged) before coming to a stop? (b) If, in actuality, a 700-kg car with an initial speed of 118 km/h is observed to coast up a hill to...
a) How high a hill can a car coast up (engine disengaged) if friction is negligible and its initial speed is 78.0 km/h? m (b) If, in actuality, a 750 kg car with an initial speed of 78.0 km/h is observed to coast up a hill to a height 10.0 m above its starting point, how much thermal energy was generated by friction? J (c) What is the average force of friction if the hill has a slope 2.5° above...
A car of mass 850 kg is initially moving at 110 km/h at the bottom of a large hill. Friction coefficient of 0.9 (rubber on dry asphalt) a) How high up the hill can the car coast (engine disengaged), if work done by friction is negligible? b) If, in actuality, the car is observed to coast up to a height of 22.o m above its starting point, how much thermal energy was generated by friction?
If a 791 kg car with an initial speed of 117.1 km/h is observed to coast up a hill to a height 22.9 m above its starting point, how much thermal energy was generated by friction? Give your answer in kilojoules.
Vo 5) h 200 m A driver coasts down a hill 200 m high with initial speed vo 40 m/s. The road has friction that results in a negative work -1.7 x 10 J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger...
A car travels up a hill at a constant speed of 40 km/h and returns down the hill at a constant speed of 60 km/h. Calculate the average speed for the round trip.
A car travels up a hill at a constant speed of 31 km/h and returns down the hill at a constant speed of 79 km/h. Calculate the average speed for the round trip.
A car drives up a straight incline of 4.8 km in length and .3 km in height. The car moves up the incline at a steady speed of 16 m s^-1, with friction force being 500 N and total weight of car and driver being 12000 N. From the top of the incline, the road continues downwards in a straight line. At the point where the road starts to go downwards, the driver stops the engine and allows the car...
A driver coasts down a hill 200 m high with initial speed vo 35 m/s. The road has friction that results in a negative work -1.7 x 10° J. The effect of this is that the total initial energy is reduced by this amount by the time the car reaches the bottom of the hill. Calculate the speed of the car when it reaches the bottom of the hill. The mass of driver and passenger is 1750 kg 59.3 m/s...
A speeding driver with a constant speed of 90.0 km/h passes a stopped police car. The police car immediately takes off after him and accelerates with a constant acceleration of 5.0 m/s2. The time needed for the police car to overtake the speeding driver is closest to …
