Question

In 2.5 s, a car increases its speed from 60 km/h to 65 km/h while a bicycle goes from rest to 5 km/h. Which undergoes the

greater acceleration?
What is the acceleration of each? (Don't forget your units when reporting answers).

Answer 1

Same, 2 km/h/s

Step-by-step explanation:

Acceleration is change in velocity over time.

a = Δv / Δt

The car's acceleration is:

a = (65 km/h − 60 km/h) / 2.5 s

a = 2 km/h/s

The bicycle's acceleration is:

a = (5 km/h − 0 km/h) / 2.5 s

a = 2 km/h/s
