Question

A bicyclist, initially at rest, begins pedaling and gaining speed steadily for 4.70s during which she covers 31.0m.

What was her final speed?

Answer 1

Answer: The final speed of the bicyclist is 6.60m/s.

Explanation:

To find the final speed of the bicyclist, we need to use the formula:

Speed = Distance / Time

We know that the distance covered by the bicyclist is 31.0m and the time taken to cover that distance is 4.70s. So, we can substitute these values into the formula:

Speed = 31.0m / 4.70s

Solving this equation, we get:

Speed = 6.60m/s

So, the final speed of the bicyclist is 6.60m/s.
