Answer 2

Calculating Time for Velocity to Reach 2 m/s

To calculate the time it takes for the cyclist to reach a velocity of 2 m/s, we can use the following kinematic equation:

v = u + at

Where: - v = final velocity (2 m/s) - u = initial velocity (0 m/s, as the cyclist starts from rest) - a = acceleration (0.2 m/s^2) - t = time

We can rearrange the equation to solve for time (t):

t = (v - u) / a

Substitute the given values: t = (2 m/s - 0 m/s) / 0.2 m/s^2

Calculating: t = 2 m/s / 0.2 m/s^2 t = 10 s

So, the time it takes for the cyclist to reach a velocity of 2 m/s is 10 seconds.
