Problem 1 You have to push with a force of 200.0 N to slide a refrigerator across the floor at constant velocity. What is the force of friction acting on the refrigerator?

Problem 2 Forces of 155 N [N] and 88 N [W] act simultaneously on an object of mass 12 kg. What is the acceleration of the object?

Problem 3 A car with a mass of 1250 kg is moving in a straight line at a speed of 30.0 m/s. It is brought to rest in 25.0 s. Calculate the force acting to stop the car.

Problem 4 Heracles is pulling a monument with a force of 1000 N [E45N]. Superman is pulling the same monument with a force of 1000 N [E45S]. Mr. Howland is pulling the same monument with a force of 100 N [W]. What is the net force on the monument?

Problem 5 A car can accelerate at 3.2 m/s2 . What is its acceleration if it is towing another car like itself?

Problem 6 Skater A (mass 50 kg) and skater B (mass 75 kg) are standing on ice. Skater A pushes Skater B with a force of 20 N [south]. Determine the acceleration (if any) of each skater.
