Answer:
A.
Explanation:
an atom that has most of its mass is electrons.
The force of friction is given by:
f = μR, where μ is the friction coefficient and R is the reaction force, which will be equal to the weight.
100 = μ x 130
μ = 0.77

v = final velocity
u = initial velocity
t = time taken
the acceleration of the cyclist is

approximately 3.33 m/s^2
the acceleration of the car is

5.0 m/s^2

You multiply force times friction
