A crate of mass 45.0 kg is being transported on the flatbed of a pickup truck. The coefficient of static friction between the crate and the truck's flatbed is 0.270, 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 crate does not slide relative to the truck's flatbed?
m/s2
(b) The truck barely exceeds this acceleration and then moves with constant acceleration, with the crate sliding along its bed. What is the acceleration of the crate relative to the ground? Your response differs from the correct answer by more than 10%. Double check your calculations.

A speedy tortoise can run at 0.01 meters per second and a hare can run 21 times as fast. In a race they both start at the same time; however the hare stops to rest for 1.50 minutes. So the tortoise wins by a shell (20 cm).
To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 50.6 m when its initial speed is 79..
