Acyclist 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 which accelerates from 0 to 30 m/s in 8 seconds

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

So:

Where

= final speed

= initial speed

= elapsed time.

Thus:

The acceleration of the cyclist is:

a = 2.667

The acceleration of the car is:

a = 3.75

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

the answer is d

step-by-step explanation:

you can also use mathway to get you answer + steps

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
