Kiko is coasting on her bicycle down a hill. After 3 s, her speed is 10 m/s. After 8 s, her speed is 25 m/s. What is her acceleration during this time?

Answer 1

We can use the formula for acceleration:

a = (vf - vi) / t

where a is the acceleration, vf is the final velocity, vi is the initial velocity, and t is the time interval.

Using the information given in the problem, we can calculate Kiko's acceleration as follows:

a = (25 m/s - 10 m/s) / (8 s - 3 s)
a = 15 m/s / 5 s
a = 3 m/s^2

Therefore, her acceleration during this time is 3 m/s^2.
