New Worksheet - Word Problems - Newton's Second Law - Part 3

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 7.9 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 2510 kg and accelerates at a constant rate of 17.1 m/s^2. How large is the force acting on the racer?

4. A 8.65 kg bowling ball would require what force to accelerate down an alleyway at a rate of 7 m/s^2?

5. Sally has a car that accelerates at 6.9 m/s^2. If the car has a mass of 1950 kg, how much force does the car produce?

6. What is the mass of a truck if it produces a force of 81,000 N while accelerating at a rate of 9 m/s^2?
