A box (350 kg) sits inside the trailer of a semitruck traveling at a speed of 15 m/s (~ 33 mph). Suddenly, a car in front of the truck stops in the road. The driver of the truck hits the brakes to bring the truck to a stop. Assume that the coefficient of static friction µs = 0.7 between the box and the floor of the trailer. Assume g = 10 m/s2. When the truck is slowing down, what is the maximum magnitude of the static friction force on box 1 (to slow it down with the truck and not let it slide)? When the truck is slowing down, what is the maximum magnitude of the truck's acceleration such that box 1 does not slide? What is the minimum time for the truck to stop such that box 1 does not slide? Use your maximum acceleration from the previous problem. Given this minimum time, what is the minimum distance for the truck to stop without box 1 sliding?

General Physics with Calc 1 8. A package of dishes (mass 50.0 kg) sits on the flatbed of a pickup truck with an open tailgate. The coefficient of static friction between the package and the truck's flatbed is 0.310, and the coefficient of kinetic friction is 0.240. (a) The truck accelerates forward on level ground. What is the maximum acceleration the truck can have so that the package does not slide relative to the truck bed? (b) The truck barely...

2. (25 points) One hauling truck is traveling on a level road. The driver suddenly applies the brakes, causing the truck to decelerate by an amount 9/3. This causes a box in the rear of the truck to slide forward. If the coefficient of sliding friction between the box and the trucked is 1/4, find the acceleration of the box relative to the truck.

A box (mass 25.8 kg) sits on a rough incline that makes an angle α = 28.1o with the horizontal. A massless string is tied to the box, runs parallel to the incline, passes over a massless, frictionless pulley, and is tied to mass M hanging on the other end. Assume μs = 0.455 is the coefficient of static friction between the box and the surface of the plane. Find the maximum value of M, in kg, for which this...

A 700 kg car is coasting along a level road, slowing down at an acceleration of 7.11 m/s^2 until coming to a stop. What is the minimum coefficient of friction between tires and roadway if this is to be possible? Assume the wheels are not locked, in which case we are dealing with static friction -- there's no sliding.
