Explanation:
The formula for this is designed around the fact that momentum must be conserved:
This is because they sitck together after they collide. Filling in:
[(3*10)+(5*2)] = [3 + 5]v and
30 + 10 = 8v so
40 = 8v and
v = 5
They are both moving east at a velocity of 5 m/s since they stuck together.

The complete question is Resistance is 440 Ω, inductance L = 0.380 H, capacitance, C = 1.4 ×10⁻² μF
43.12 V
Explanation:
Find the current through the capacitor.
At resonance, impedance Z = R
V = IR
V = 0.098 × 440 = 43.12 V
