Answer:
His acceleration was -1/5 m/s²
Step-by-step explanation:
We can find the acceleration by using the formula to find the final velocity in terms of initial velocity and acceleration and then solving for a. The formula is V2 = V1 + (a)(t) where V2 is final velocity, V1 is initial velocity and t is time in seconds.
We are going to substitute the values given in the problem:
V2 = 0 m/s
V1 = 6 m/s
t = 4 seconds
Therefore, his acceleration was -1.5 m/s²

<u>Solution:</u>
Given that , we have to find fractions which has the same value as that of the fraction
Now, we know that, there are several fractions with values equal to
To find them, just multiply the numerator and denominator by the same number.
Therefore, is equal to
We can do the same with 4, to get , or any other number beyond that.
Hence, one of the fractions that’s equal to is
Substitute <em>u</em> = <em>t</em> ³/2592 and d<em>u</em> = <em>t</em> ²/864 d<em>t</em>. Then
The probability that a 12 hour surgery is successful is <em>P</em> (12), so letting <em>T</em> = 12 gives
