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.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
