# Newton's 2nd Law Practice Sheet 2

- Your bicycle has a mass of 9.1 kilograms. You accelerate at a rate of 1.79 m/s
^{2}. Calculate the net force that is accelerating the bicycle.
- The Space Shuttle has a liftoff mass of 2,041,000 kg and accelerates at a rate of 16 m/s
^{2}. Calculate the force (thrust) that is accelerating the Space Shuttle.
- A rocket accelerates at 56 m/s
^{2}. It has a mass of 800,000 kg. Calculate the force (thrust) that the rocket engines must supply.
- A runner has a mass of 89 kilograms. He produces a force of 84 Newtons between the ground and his running shoes. How fast does he accelerate?
- Calculate the acceleration of a car if the force on the car is 450 Newtons and the mass is 1300 kilograms.
- Calculate the acceleration of a jet car racing on the Bonneville Salt Flats if the force on it (the “Thrust”) is 500,000 Newtons and the mass is 2,100 kilograms.
