Calculate the acceleration if you ride your bike down hill and the initial velocity is 2 km/hr and the final velocity is 23 km/hr and it takes you. 25 hours to go down the hill

We can calculate the acceleration by using a kinematic equation that relates what is given to us with respect to acceleration. In the problem, we are given:

Vi = 2 km/hr

Vf = 23 km/hr

t = 0.25 hours

The kinematic equation that relates these values is:

Vf = Vi + at

Plugging in these values, we find that:

23 = 2 + a (0.25)

a = 84 km/hr^2

The acceleration of your bike is 84 km/hr^2.
