Question

Shawn and his bike have a total mass of 48.4 kg. Shawn rides his bike 1.9 km in 13 min at a constant velocity. What is Shawn's acceleration?

a. 0 m/s²
b. 0.1 m/s²
c. 0.2 m/s²
d. 0.3 m/s²

Answer 1

Shawn's acceleration is 0 m/s² since he is riding at a constant velocity, indicating no change in speed over time.

Step-by-step explanation:

If Shawn and his bike have a total mass of 48.4 kg and he rides his bike 1.9 km in 13 minutes at a constant velocity, then his acceleration is 0 m/s². Acceleration is defined as the change in velocity over time, and since Shawn is moving at a constant velocity, there is no change in his speed and therefore no acceleration. Thus, the correct answer is (a) 0 m/s².
