Problem
A cyclist and bicycle together have a mass of 80 kg. While moving in a straight line on a level road at 6 m s−1, the rider applies the brakes that provide a constant opposing force of 100 N.
Using this information, answer the parts below.
(i) Determine the initial momentum of the system.
(ii) Calculate the deceleration produced by the brakes.
(iii) Find the time taken for the bicycle to come to rest.
(iv) Compute the distance travelled by the bicycle during braking.
