Question

A person starts walking at 1 m/s. What is the acceleration of this person if the walker increases their speed to 3 m/s in a period of 2 seconds? Please show your work.

Answer 1

The acceleration of the person whose initial walking speed increases to the new speed at the given time is 1.0m/s².

What is Motion?

Motion is simply the change in position of an object over time.

From the First Equation of Motion;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

Given the data in the question;

• Initial velocity of the man u = 1m/s

• Final velocity of the man v = 3m/s

• Elapsed time t = 2.0s

• Acceleration of the man a = ?

To determine the acceleration of the person, we substitute our given values into the expression above.

v = u + at

3m/s = 1m/s + (a × 2.0s)

a × 2.0s = 3m/s - 1m/s

a × 2.0s = 2m/s

a = 2m/s ÷ 2.0s

a = 1m/s²

Therefore, the acceleration of the person whose initial walking speed increases to the new speed at the given time is 1.0m/s².
