Question

A student pedaling a bicycle applies a net force of 400 N. The mass of the rider and the bicycle is 25 kg. What is the acceleration of the bicycle and the rider?

Answer 1

The acceleration is $16 m/s^2$

Explanation:

We can answer this question by using Newton's second law, which states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:

$F=ma$

where

F is the force

m is the mass

a is the acceleration

In this problem, we have

m = 25 kg is the mass of the rider+bicycle

F = 400 N is the force

Solving for a, we find the acceleration:

$a=\frac{F}{m}=\frac{400}{25}=16 m/s^2$
