Homework Statement An ant clings to the outside edge of the tire of an exercise bicycle. When you start pedaling, the an't speed increases from ) to 10 m/s in 2.6 s. The wheel's rotational acceleration is 13 rad/s^s. Determine the average tangential acceleration of the tire. Homework...

So you would say that Ff=ma and Ff=μmg, then set them equal to each other so the mass cancels out? That makes sense, i'll try that. Thanks!

A 50 kg box rests on the floor. The coefficients of static and kinetic friction are 0.70 and 0.50, respectively. a.) What is the minimum force required to start the box sliding from rest? b.) After the box starts sliding, the person continues to maintain that force. What is the...

A car traveling at 97 km/h can stop in 48 m on a level road a.) Determine the acceleration of the car b.) Determine the coefficient of friction between the tires and the road Homework Equations : Vf^2=Vo^2 +2aΔx μ=Ff/mg[/B] 3. I have part A, I got -7.53 m/s^2, but I can't seem to...
