A bicycle takes 8.0 seconds to accelerate at a constant rate from rest to a speed of 4.0m/s. If the mass of the bicycle is 86 kg, what is the net force acting on the bicycle? (Hint: You need to first calculate the acceleration of the bicycle)

Answers

Answer 1

Explanation:

acceleration = final velocity- initial velocity/time taken

acceleration =4.0m/s -0 m/s / 8 seconds

acceleration =4/8

acceleration =1/ 2

acceleration =0.5 ms^2

force = mass × acceleration

f = 86kg×0.5= 43 newtons
