When stopping a car on an icy or wet road... or a dry road, for that matter... is it better to push the brake pedal hard enough to lock the wheels and make them slide? Or to push gently so that the wheels continue to roll? What is the point behind "anti-lock disk brakes"? Which coefficient of friction Hs or µk is relevant to which case? (hint: start by considering the forces on different points on the wheel in each case, and calculate the largest possible deceleration for both conditions)

DESIGN CHANGE.  Now: The Object weighs 100 lb The angle of P above the horizontal is 42 degrees The coefficient of static friction is 0.6     The magnitude of the maximum P that will not initiate motion of the Object is _____lb.

The coefficient of static friction between the 200-kg crate and the flat bed of the truck is 0.25. (Figure 1) Figure 1 of 1 Part A Determine the shortest time for the truck to reach a speed of 65 km/h, starting from rest with constant acceleration, so that the crate does not slip.
