The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car's average acceleration?

Acceleration,

Step-by-step explanation:

Given that,

Initial speed = 4 m/s at 2 seconds

Final speed = 32 m/s at 9 seconds

We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,

So, the car's average acceleration is equal to .

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
