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 distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
