A vehicle of mass 2000 kg has a constant resistance to motion of 3000 N. The maximum speed of the vehicle, when travelling on a horizontal road, is 120 km/hour. Find the acceleration of the car when it is travelling at a speed of 50 km/hour up a hill inclined at an angle of 3o to the horizontal, with the engine operating at maximum power (assume the resistance to motion remains unchanged whether the car is travelling uphill or horizonally...
A car of mass 1000 Kg descends a hill inclined with horizontal by 30°, the car is traveling at 80 km/h is uniformly brought to rest over a distance of 40 m. Calculate using work-energy method the average braking force required. The resistance to the motion is 200 N. 40 0 = 30°
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 of mass 1570 kg traveling at 24.0 m/s is at the foot of a hill that rises 100 m in 2.20 km. At the top of the hill, the speed of the car is 8.0 m/s. Find the average power delivered by the car's engine, neglecting any frictional losses.
A car of mass 1510 kg traveling at 22 m/s is at the foot of a hill that rises 115 m in 2.2 km. At the top of the hill, the speed of the car is 12 m/s. Find the average power delivered by the car's engine, neglecting any frictional losses. (In watts)
9. A car of mass 1550 kg traveling at 27.0 m/s is at the foot of a hill that rises 110 m in 2.60 km. At the top of the hill, the speed of the car is 14.0 m/s. Find the average power delivered by the car's engine, neglecting any frictional losses. Watts
