A resistor with R = 320Ω, a capacitor with C = 18x10∧-6F and an inductor with L = 30x10∧-3H are connected in series to a voltage source with Em = 36V and f = 60Hz. Determine the value of the circuit impedance, the angle phase and current amplitude.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
