Answer:
a = 0.5 m/s²
Explanation:
Given that,
Initial velocity, u = -3 m/s (west)
Final velocity, v = -1 m/s (west)
Time, t = 4 s
We need to find the acceleration of Alex. Acceleration of an object is the rate of change of velocity per unit time. So,

So, her acceleration is 0.5 m/s². Hence, the correct option is (c).
