Question

14. Whitney is about to go skiing down a hill with her friends. She
changes her velocity from 0 m/s to 18 m/s in 9 seconds. What is
Whitney's acceleration in that 9 seconds? Formula: a = VF - Vilt
OA.
9 m/s?
18 m/s?
2 m/s2
5 m/s2

Answer 1

Answer:

2 m/s²

Explanation:

Acceleration (a)= rate of change of velocity = (final velocity- initial velocity)/ time taken

So we get,

a = (18-0)/9 = 2 m/s²
