A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration? Is this acceleration higher than that of a car
77julia77 [94]

The average acceleration of an object is calculated as the final speed minus the initial speed divided by the elapsed time.

So:

a = \frac{V_f-V_0}{T_2-T_1}

Where

V_f= final speed

V_0 = initial speed

T_2-T_1 = elapsed time.

Thus:

The acceleration of the cyclist is:

a = \frac{8-0}{3}

a = 2.667m / s ^ 2

The acceleration of the car is:

a = \frac{30-0}{8}

a = 3.75 m/s^2

The average acceleration of the car is higher than the average acceleration of the cyclist.
