1.what is a sports car average acceleration if it can go from 0m/s to 27m/s in 6.0 seconds?

Flauer [41]

Answer:

1.4.5m/s^2

2.6.25m/s^2

3.15m/s^2

4.0.05m/s^2

Step-by-step explanation:

a=v-u

----

27-0

------ = 27/6

=4.5m/s^2

u=4.5m/s

v=24.5m/s

t=3.2s

(24.5-4.5)÷3.2

=20/3.2

=6.25m/s^2

v=80m/s

u=50m/s

t=2s

(80-50)÷2

15m/s^2

v=0.80m/s

u=0.50m/s

t=6s

(0.80-0.50)÷6

=0.05m/s^2

Does anyone know the answer?I am stuck? Please explain it to me!

We are given the length of AC and AB to be 20 and 6, respectively, so we can subtract 6 from 20 to find BC to be 14 cm.

The circumference of a circle is equal to $2 \pi r$

$C=2 \pi (14) = 28 \pi$

The answer is approximately 87.96 cm
