When the decrease in velocity (the acceleration) is uniform, the average velocity is [Initial velocity - Final velocity]/2
We know tha the initial velocity is 0.96 rev / sec and the final velocity is 0,
Then, the average velocity is [0.96 / 2 ]rev /sec = 0.48 rev/sec.
Also, by defintion,
average velocity = number of rev / time,
From which, number of rev = average velocity * time
So, number of rev = 0.48 rev/sec * 2.4 min * 60sec /min = 69.12 rev
Answer: 69.12 revolutions
Answer:

Answer:
Hi there!
The correct answer is: 220.5 cm²
Step-by-step explanation:
This is an example of a composite figure where you have to break up the figure into different shapes. In this case this figure, can break up into a semicircle and a triangle.
<u>Triangle:</u> A= 1/2bh A=1/2(16)(15) = 120 cm²
<u>Semicircle: </u>another way of saying half a circle so A= 1/2 πr²
A=(1/2)(π)(8)² = 100.5 cm²
And then you just add the two areas together and you get 220.53 cm²
