Answer:
Acceleration,
Explanation:
It is given that,
Mass of Gary, m = 80.5 kg
Mass of his bicycle, m' = 13.7 kg
Net unbalanced force acting on him, F = 9.86 N
Let a is the value of acceleration. Both cycle and Gary will move with same acceleration. Using the second law of motion to find it as :
or
So, the value of acceleration of the Gary and bicycle is . Hence, this is the required solution.
