Answer:
S(-7,0) , 2/7
Step-by-step explanation:
To get coordinates of P we can see that
14*(2/7)=4
Now, to get coordinates of S, we have this equation :
Multiply by 7 each side :
2x=-14
x=-7
y=0
Answer:
160,000 Nm
2667 Nm/sec
Step-by-step explanation:
Work = weight * distance
= 800 * 200
= 160,000 Nm
Power = rate of work done
= 160,000 / 60
= 2667 Nm/sec
The answer is C because x2 is a parabola
