A westward-moving bicycle increased its speed from 2.0m/s to 12.0m/s in 4.0 seconds. What is the magnitude and direction of the acceleration?

Respuesta :

Magnitude and direction of the acceleration is 2.5 m/s² (Toward west)

Given that;

Initial speed of car = 2 m/s

Final speed of car = 12 m/s

Time taken = 4 second

Find:

Magnitude and direction of the acceleration

Computation:

Acceleration = [v - u] / t

Magnitude and direction of the acceleration = [12 - 2] / 4

Magnitude and direction of the acceleration = 10 / 4

Magnitude and direction of the acceleration = 2.5 m/s² (Toward west)
