Answer:
(a) Velocity of target is 2.7 m/s.
(b) Mass of target is 0.807 kg.
Explanation:
Mass of ball 
initial speed of the ball 
Final speed of the ball 
Part (a) The second ball is initially at rest. So, by the conservation of momentum,
Now, the velocity of approach is equal to the velocity of separation,
Part (b): From equation (1),
TLDR: R=30 Ohms, I=2 Amps, 12V, 28V, 20V, respectively.
Alright, let’s break this down. There are three resistors in this circuit, meaning that we have to find the equivalent resistance. Luckily, they are all in parallel with one another; this means we can add the resistances together without having to do inverses like in a series problem. This means that the equivalent resistance, Req, would equal:
Req=R1 + R2 + R3
Req=6 + 14+ 10
Req=30 Ohms
This means that we could theoretically replace all three resistors with a 30 Ohm resistor and accomplish the same goal. Now, the entire voltage of the system would normally be reduced to zero after passing through the resistors - in this case, the 60 Vs would be lost after passing through 30 Ohms. This means we’re losing 2V/Ohm; now we can figure out how much we’re losing at each resistor.
By losing 2V per Ohm, we’re losing 12 V at the first resistor, 28 V at the second resistor, and 20 V at the third resistor.
Finally, we can calculate the current through the circuit; for a series circuit, the current remains the same. Using V=IR, we can find that:
V=IR
60 V = I(30 Ohms)
I = 2 Amps
The current passing through the circuit is 2 Amps.
Hope this helps!
