Word Problems – Newton's Second Law Worksheet - Part 2

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

1. A 52-kg water-skier is being pulled by a speedboat. The force causes her to accelerate at 2 m/s^2. What is the force?
___________________

2. How much force is needed to accelerate a 1000-kg elevator at 2 m/s^2?
___________________

3. What is the force needed to accelerate a 55-kg cart at 15 m/s^2?
___________________

4. Assume that a catcher in a professional baseball game exerts a force of 65.0 N to stop the ball. If the baseball has a mass of 0.145 kg, what is its acceleration as it is being caught?
___________________

5. A 214 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 1310 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 2850 N. This force causes the house to move with an acceleration of 0.03 m/s2. What is the mass of the house?

New Worksheet - Word Problems – Newton's Second Law - Part 1

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

1. The tallest man-made structure at present is the Warszawa Radio mast in Warsaw, Poland, This radio mast rises 646 m above the ground, nearly 200 m more than the Sears Tower in Chicago. Suppose a worker at the top of the Warszawa Radio mast accidentally knocks a tool off the tower. If the force acting on it is 3.6 N, and its acceleration is 9.8 m/s^2, what is the tool’s mass?
___________________

2. In drag racing, acceleration is more important than speed, and therefore drag racers are designed to provide high accelerations. Suppose a drag racer has a mass of 1250 kg and accelerates at a constant rate of 16.5 m/s^2. How large is the force acting on the racer?

3. What net force is required to accelerate a car at a rate of 2 m/s^2 if the car has a mass of 3,000 kg?
___________________

4. A 10 kg bowling ball would require what force to accelerate down an alleyway at a rate of 3 m/s^2?
___________________

5. Sally has a car that accelerates at 5 m/s^2. If the car has a mass of 1000 kg, how much force does the car produce?
___________________

6. What is the mass of a truck if it produces a force of 14,000 N while accelerating at a rate of 5 m/s^2?
