Question

A biker increased his velocity from 2 m/s to 8 m/s in 3 seconds moving in a straight line. what is the acceleration of the biker?

Answer 1

To determine the biker's acceleration, the final velocity minus the initial velocity is divided by time, resulting in an acceleration of 2 m/s².

Step-by-step explanation:

To calculate the acceleration of the biker, we can use the formula for acceleration which is:

a = (vf - vi) / t

where:

• vf is the final velocity,
• vi is the initial velocity,
• t is the time period over which the acceleration occurs.

Substituting the given values into the formula:

a = (8 m/s - 2 m/s) / 3 s

The biker's acceleration is:

a = 6 m/s² / 3 s

a = 2 m/s²

The biker's acceleration is 2 meters per second squared, indicating that the velocity increases by 2 m/s every second.
