I watched a lot of Looney Toons when I was a kid, and liked that the Roadrunners legs would spin for a second or two before their claws caught traction. a. With a coefficient of kinetic friction 0.2 what acceleration will the roadrunner experience while their feet are sliding accross the ground? b. How far forward will the roadrunner drift in a half second, starting from rest under this acceleration? c. After catching traction the Roadrunner accelerates away, travelling 10 m to get offscreen in one fifth of a second. What was their coefficient of static friction?
