A kid has 650 Joules of potential energy when they are the top of their swing. If the height is 1.3 meters, what is the mass of
the kid?
1 answer:
Answer:
51kg
Step-by-step explanation:
GPE=mass×gravitational field strength×height
so...
mass=GPE/gravitational field strength×height
gravition field strength on earth=9.81
650/9.81×1.3=50.968...

0.07x+0.08 (9000-x)=700
Solve for x
0.07x+720-0.08x=700
0.07x-0.08x=700-720
-0.01x=-20
X=20÷0.01
X=2,000 invested at 7%
9000-2000=7000 invested at 8%
