A 2.00 kg remote controlled car is equipped with a single electric motor that provides the car with the power necessary for it to accelerate. a. The maximum power rating of the electric motor is 168 Watts. Using the motor at this maximum rated power, how long will it take to accelerate a 2.00 kg car from 5.00 m/s to 14.5 m/s if we neglect all frictional losses? b. Calculate the average acceleration of the car during this period. c....

Question5 Each of the two wheels of a motor bike have a mass of mw-11 kg, radius of rw 320 mm, and radius of gyration kw 0.24 m. The motor bike and rider with a total mass of m 208 kg travel round a bend of radius R = 80 m at a speed of 135 km/h. The engine rotates in the same sense as the wheels and at four times their speed. The engine rotating parts have a mass...

The car shown has a mass of m=1000 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is μs=0.250. The dimensions are a=1.15 m, b=1.55 m, and c=0.290 m. Assume the car starts from rest, the wheels do not slip on the road, and that the car experiences constant acceleration. Neglect the mass of the wheels. Part A - Shortest Time to Reach a Given Speed with Rear-Wheel Drive...

Question 2 (a) A small electric vehicle is propelled by a motor with the performance data shown in Figure Q2 below. The motor drives a gear with 12 teeth, which in turn drives a larger gear, which is attached to the vehicle's driving wheels. The diameter of the driving wheels is 380 mm and the vehicle is designed for a speed of 30 km/h. (Note: Errors of +10% in reading data from the graphs are acceptable for the purposes of...
