Question

What is the acceleration of a bicyclist who accelerates from 0 m/s to 11 m/s in 4.5 seconds?

a) 1.5 m/s²
b) 2.0 m/s²
c) 2.5 m/s²
d) 3.0 m/s²

Answer 1

The acceleration of the bicyclist who accelerates from 0 m/s to 11 m/s in 4.5 seconds is 2.0 m/s².

Step-by-step explanation:

To find the acceleration of the bicyclist, we can use the equation:

Acceleration = (Final velocity - Initial velocity) / Time

Given that the initial velocity is 0 m/s and the final velocity is 11 m/s, and the time taken is 4.5 seconds, we can substitute these values into the equation:

Acceleration = (11 m/s - 0 m/s) / 4.5 s

Acceleration = 11 m/s / 4.5 s

Acceleration = 2.44 m/s²

Therefore, the correct answer is option b) 2.0 m/s².
