Question

In order to ride a bike up a hill with increasing speed—

the rider’s pedal force must be less than friction and the force of gravity
the rider’s pedal force must be equal to than friction and the force of gravity
the rider’s pedal force must be greater than friction and the force of gravity
It is impossible to ride up a hill with increasing speed.

Answer 1

Answer: the rider’s pedal force must be greater than friction and the force of gravity

Step-by-step explanation:

This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.
