A man in a flat bed truck starts from rest up a hill at an angle of 8 degrees. If he is carrying a 600 kg crate in the back and the static coefficient of friction is 0.25, what is the maximum rate of acceleration before the crate slides off of the back of the truck? How long will it take the truck to 600 kg reach a speed of 30 m/s?

A spherical bowling ball with mass m = 4.6 kg and radius R = 0.105 m is thrown down the lane with an initial speed of v = 9.5 m/s. The coefficient of static friction between the ball and the ground is 0.35 and the coefficient for kinetic friction is μ = 0.3. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down the lane? 2) What is magnitude of the linear acceleration of the bowling ball as it slides down the lane? 3) How long does it take the bowling ball to begin rolling without slipping? 4) Once it begins to roll without slipping, what is the force of friction on the ball?
