Given information
As per the given question ,
- A bicyclist in the Tour de France crests a mountain pass as he moves at 15 Km/h
- At the bottom, 4.0 km farther, his speed is 65 Km/h
Step-by-step explanation
Step 1.
First we go to take the movement as a movement in one dimension only (in the direction of the travel of the bicyclist).
To calculate the average acceleration we need take the movement as uniformly accelerated (where the acceleration is the average acceleration), the two principal equation are:
Replacing the equation (2) in eq. (1):
with that equation, we can calculate the acceleration.
