Question
Calculate the acceleration of the bicycle of mass 25 kg as shown in Figures 1 and 2.
Solution
Given:
Mass of bicycle m = 25 kg
Fig. I:
Net force acting in the forward direction, F = 500 –
400 = 100 N
acceleration a = `F/m = 100/25` = 4 ms-2
Fig. II:
Net force acting on bicycle F = 400 – 400 = 0
∴ acceleration a = `F/m = 0/25` = 0
