New Worksheet - Word Problems - Newton's Second Law - Part 4

Solve the following word problems using this formula: force = mass x acceleration

1. A 47-kg water-skier is being pulled by a speedboat. The force causes her to accelerate at 9 m/s^2. What is the force?
___________________

2. How much force is needed to accelerate a 1200-kg elevator at 1.9 m/s^2?
___________________

3. What is the force needed to accelerate a 14-kg cart at 5.5 m/s^2?
___________________

4. Assume that a catcher in a professional baseball game exerts a force of 68.0 N to stop the ball. If the baseball has a mass of 0.213 kg, what is its acceleration as it is being caught?

5. A 428 kg boat is sinking in the ocean. The force of gravity that draws the boat down is partially offset by the buoyant force of the water, so that the net unbalanced force on the boat is 3100 N. What is the acceleration of the boat?
___________________

6. A house is lifted from its foundations onto a truck for relocation. The unbalanced force lifting the house is 2920 N. This force causes the house to move with an acceleration of 0.17 m/s2. What is the mass of the house?
