Question: A 90 kg metal slab is pulled across the ground by a tractor. The coefficient of friction between the slab and the ground is µ = 0.65. If the force of the tractor on the slab is 600 N and is directed at 35° from the horizontal,
Part A: What is the acceleration of the slab?
Please show steps and all work to find the acceleration of the slab.
