Question: Find the net force including its direction when each force acts in the direction indicated. 1. Find the acceleration of an automobile of mass 1500

Find the net force including its direction when each force acts in the direction indicated.
1. Find the acceleration of an automobile of mass 1500 kg acted upon by a driving force of 2200 N that is opposed by a frictional force of 450 N.
2. A truck of mass 13,100 kg is acted upon by a driving force of 8900 N. The motion is opposed by a frictional force of 2230 N. Find the acceleration.
3. A speedboat of mass 30.0 slugs has a 300-lb force applied by the propellers. The friction of the water on the hull is a force of 100 lb. Find the acceleration.
4. A truck with a mass of 14,000 kg is pushed with a force of 9200 N. If the frictional force is 2150 N, what is the truck’s acceleration?
5. A trailer has a mass of 5000 kg. It is pulled by a truck with a force of 8750 N. If the frictional force is 2000 N, what is its acceleration?
6. A refrigeration unit on a job site must be slid into place. If the frictional force of 975 N opposes the motion and two workers apply a total force of 1095 N to the unit, what is the net force on the unit?
7. A light truck of 2000 kg mass has to be pushed with a force of 1975 N. If the frictional force is 550 N, what is its acceleration?
