Answer:
Explanation:
<u>First person:</u>
the rock is dropped
after t1 seconds it hit the ground, y(t)=0
<u>Second person:</u>
the rock has a initial downward speed
after t2 seconds it hit the ground, y(t)=0
the time t when the second person throws the rock after the first person release the rock is:
t=t1-t2
D = m/v
2.7 = 3/x
2.7x = 3
x = about 1.11
For the resistor closest to the battery, drawn vertical in the diagram, I = 8 A and P = 320 watts.
Also, the battery voltage is 40 V.
There isn't enough information included in the picture to fill in any of the missing items for the other two resistors.
should be 1
