Explanation:
We have,
Initial speed of bicycle, u = -10 m/s (westward direction)
Final speed, v = -4 m/s (westward direction)
Time, t = 3 s
It is required to find the magnitude and the direction of the acceleration. It is equal to the change in velocity divided by time taken.
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{(-4)-(-10)}{3}\\\\a=2\ m/s^2[/tex]
The acceleration of the bicycle is [tex]2\ m/s^2[/tex]. It is in eastward direction.
