  1. 1. [15 pts] A man drags his 35.0 kg suitcase across the ground with a force that is directed 50° above the horizontal. The coefficient of static friction between the suitcase and the ground is 0.450, and the coefficient of kinetic friction is 0.330. a. What is the minimum force the man needs to exert to get the suitcase moving from rest?b. If he continues to exert the same amount of force once the suitcase begins to move, what will be the acceleration of the suitcase?

A truck drags a 200 kg log, initially at rest, across the (flat) ground for 10 meters, and then up a 30-degree incline. If the truck pulls with a constant force of 20,000 Newtons, and the coefficient of friction between the wood and ground is 0.2 for the entire duration of the journey, once log has traveled 10 meters along the incline, what is the log’s speed in m/s? Hint: use conservation of energy to solve this problem, using the...
