1. if a car is speeding off on a surface of asphault, no slipping tires, estimate static friction for a drag racer that covers the quarter mile in 6 seconds My attempt: I made a Free Body Diagram: Weight (W) down wards, Normal force (fn) upwards, and friction static friction to the...

okay, i tried searching knietic energy and it won't come up, soooo here's a questions: a force of 40 N continues to push a 5 kg box and acclerates it a .70 m/s/s what is the coefficient of friction/ i got the static because it wasn't movingm, but i have no idiea how to get that please...
