find the deceleration of a cyclist reduces from 2.5m/s to 1.0 m/s in 12s?
a = (Vf - Vo) / t,
a = (1.0 - 2.5) / 12 = -0.125 m/s^2.
thanks
To find the deceleration, you can use the formula:
Acceleration = (Change in Velocity) / Time
Given that the initial velocity (u) is 2.5 m/s, the final velocity (v) is 1.0 m/s, and the time (t) is 12 seconds, we can plug these values into the formula to calculate the deceleration.
Acceleration = (v - u) / t
Acceleration = (1.0 m/s - 2.5 m/s) / 12 s
Acceleration = (-1.5 m/s) / 12 s
Simplifying the equation:
Acceleration = -0.125 m/s^2
Therefore, the deceleration of the cyclist is -0.125 m/s^2. The negative sign indicates that the cyclist is decelerating or slowing down.
