Susan rolls downhill on her bicycle. moving with a speed of 6.0 meters per second, her speed increases to 12.0 meters per second in 6.0 seconds. calculate the acceleration rate of the susan.

a = 1 m/s²

Explanation:

Definition:

The acceleration is rate of change of velocity of an object with respect to time.

Formula:

a = Vf - Vi/t

a = acceleration

Vf = final velocity

Vi = initial velocity

t = time

Units:

The unit of acceleration is m.s⁻².

Given data:

Initial velocity = 6 m/s

Final velocity = 12 m/s

Time = 6 s

Acceleration = ?

Solution:

a = Vf - Vi/t

a  =12 m/s - 6 m/s / 6 sec

a =   6 m/s / 6 sec

a = 1 m/s²
