to 1 m/s west in 4 seconds. What was her acceleration?
O A. -2 m/s2 west
O B. -4m/s2 west
OC. 0.5 m/s² west
OD. -3 m/s² west
O A. -2 m/s2 west
O B. -4m/s2 west
OC. 0.5 m/s² west
OD. -3 m/s² west
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).
