Calculating Bike Rider's Acceleration
Calculating Acceleration of a Bike Rider
If a bike rider slows from 7.0m/s to 2.0m/s in 4.90s, what is the bike rider's acceleration?
Question:
If a bike rider slows from 7.0m/s to 2.0m/s in 4.90s, what is the bike rider's acceleration?
Answer:
-1.02 m/s²
Explanation:
Acceleration is change in velocity over time.
a = Δv / Δt
a = (2.0 m/s − 7.0 m/s) / (4.90 s)
a = -1.02 m/s²
