A cyclist accelerates from rest at a rate of 1.00 m/s2. How fast will a point on the rim of the tire?

A cyclist accelerates from rest at a rate of 1.00 m/s2. How fast will a point on the rim of the tire (diameter = 68 cm) at the top be moving after 1.1 s? (Hint: At any moment, the lowest point on the tire is in contact with the ground and is at rest.Can someone please show me how his is done? i have no idea what i am doing? thanks

okay there are quite a few steps to this problem.The equation that will solve this problem is v=2*r*w There are steps that we need to find these.1. to find r we will divide the diameter 68 cm by 2 to get the radius 68cm/2= 34cm2. to find omega (w) we will use the formula w=wi+alpha*twe need to use this formula to find alpha: alpha=a/r alpha is 1/34. so just plug into the formula w=wi+alpha*t =0+(1/34)(1.1) w =0.0323529412so to solve the whole problem is the formula v=2*r*w v=2*34*0.0323529412 =2.2 m/sI hope this helps if you.......
