A boxed cake is placed in the trunk of a car to be delivered to a birthday party. The coefficient of static friction is 0.15 and for kinetic friction is 0.11. What is the minimum 0-60 mph time that the car can accelerate and keep the box from sliding? In other words, what is the shortest time for the driver to accelerate from a stop up to 60 mph and not have the box slide back...

If the applied force P = 250 N, determine (a) the required
minimum compression in the spring so that the wedge will not move
to the right. Neglect the weight of A and B. The coefficient of
static friction for all contacting surfaces (i.e. between B &
A, and A & C) is ? = 0.35. Neglect friction at the rollers.
