"he wheels {with tires) on a vehicle have a radius of about 0.35 m and a mass of around 26.3 kg. For simplicity, we will treat the mass as evenly distributed, so the wheels can be treated as a disc. The entire vehicle, including the wheels, has a mass ofabout 1000 kg. "he vehicle accelerates from rest to w: 34.6 mfs in 21 seconds along a straight, flat road. How many revolutions will each wheel have made in those 21 seconds? What is the rotational velocity [angular velocity] of each wheel when the vehicle reaches Vf? [This is a vector, so you need to specify a direction. Use directions relative to the direction the car is traveling like forward, backward, left, right, up, and down.) Compare the total rotational kinetic energy of the wheels at any nonzero speed to the translational kinetic energy of the vehicle at that same speed. (This tells you something about the work done by the engine. How much work must the engine do to spin the wheels compared to how much work it must do to overcome the inertia of the whole vehicle?] After accelerating to v5 the vehicle enters a flat curve that has a radius of 140 m. If it maintains the same speed, what acceleration does the car experience as it rounds the curve? What minimum coefficient of friction between the road and tires is necessary to keep the car from sliding off the road
