Calculating the Distance Traveled by the Cyclist

The cyclist accelerates from rest to a speed of 10 m/s in 5 seconds. We need to find the distance traveled by the cyclist in the first 3 seconds.

To calculate the distance traveled by the cyclist in the first 3 seconds, we can use the equation:

distance = initial velocity * time + 0.5 * acceleration * time^2

Given: - Initial velocity (u) = 0 m/s (as the cyclist starts from rest) - Final velocity (v) = 10 m/s - Time (t) = 3 seconds - Acceleration (a) = ?

First, we can calculate the acceleration using the formula:

acceleration = (final velocity - initial velocity) / time

Substitute the given values: acceleration = (10 m/s - 0 m/s) / 5 s = 2 m/s^2 Now, we can use the calculated acceleration to find the distance traveled in the first 3 seconds:

distance = (0 m/s * 3 s) + 0.5 * 2 m/s^2 * (3 s)^2 distance = 0 m + 0.5 * 2 m/s^2 * 9 s^2 distance = 0 m + 9 m distance = 9 meters

So, the cyclist travels a distance of 9 meters in the first 3 seconds.
