“A car of mass 500 kg is travelling at 20 m/s. The driver sees a red traffic light ahead and slows to a halt in 10 s. Calculate the braking force provided by the car.” (Sang et al. 2014, p. 39) | A car with a mass of 800 kg experiences a constant braking force of 400 N. If the car comes to a halt from an initial velocity of 15 m/s, calculate the time it takes for the car to stop. |
