1. A cyclist accelerates from rest at a rate of 0.80 m/s^2. How fast will a point on the top of the tire rim (diameter = 68cm) be moving after 4.0 s? (hint: At any given moment, the lowest point on the tire is in contact with the ground and hence is at rest.) 2. What is the max speed with which a 1000kg car can round a turn of radius 100m on a flat road if the coefficient of friction between the tires and road is 0.5? Is the result independent of the mass of the car? I need some assistance on how to go about doing the questions. What equations do I use where?
