Question

The coefficients of friction between a 250-lb football sled and the grass are μs = 0.6 and μk = 0.4. For grass and cleats, μs = 0.9. Three potential walk-ons are trying to impress Urban Meyer. The second walk-on is 220 lb but exerts a horizontal push of 190 lb. Calculate the sled’s acceleration. Round the final answer to two decimal places.
