Step-by-step explanation:
Answer:
t = 6.2/s miles/minute
Step-by-step explanation:
Average speed is defined as the rate of change in distance of a body. Mathematically; speed = Distance/Time
Given the distance of the runner in miles to be d = 6.2miles
Time taken = t
Average speed = s
To express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;
s = D/t
Substituting D = 6.2miles into the formula;
s = 6.2/t
Cross multiply
St = 6.2
Divide both sides by 's'
st/s = 6.2/s
t = 6.2/s
Hence, the equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute
Answer:
[8i + 54j + 72k] joules per newton metre square.
Step-by-step explanation:
F(x,y,z) = z2i + 3xyj + 3y2k
F(3,0,0) = 0
F(3,3,1) = 1(2i) + 3(3)(3)j + 3(3)(2k)
= 2i + 27j + 18k
F(0,3,1) = 1(2i) + 3(0)(3)j + 3(3)(2k)
= 2i + 18k
The sum = [4i + 27j + 36k]
Since the particle moves back to the origin, we multiply the above Work Done by 2:
[8i + 54j + 72k]
And since work done is the product of Force and Distance, the S.I. unit is Joules/newton metre square
