Question

A car starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds. What is its acceleration? What is the car’s displacement? (Demonstrate by two methods.)

Answer 1

The acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².

How to calculate acceleration?

The acceleration of a moving object can be calculated using the following formula:

a = (v - u)/t

Where;

• a = acceleration (m/s²)
• v = final velocity (m/s)
• u = initial velocity (m/s)
• t = time (s)

According to this question, a car starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds.

a = (25.5 - 12.5)/5

a = 13.0/5

a = 2.6m/s²

Therefore, the acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².
