Let's assume that the coordinate system is defined as positive in the first quadrant.
The system has its origin in the place where Ingrid kicks the football ball.
We have then that the horizontal component is given by:
Rewriting we have:
Rounding the obtained result we have:
Answer:
The horizontal component of the initial velocity to the nearest tenth is:
When a camera uses a flash, a fully charged capacitor discharges through an inductor. In 4 * seconds must the 0.100-A current through a 2.00-mH inductor be switched on or off to induce a 500-V EMF.
When a Capacitor is connected to a circuit with Direct Current (DC) source, two processes, which are called "charging" and "discharging" the Capacitor
Given
Inductance = 2 m H
EMF = 500 V
Current = 0.100 A
EMF = L (di/dt)
dt =
L di / EMF
t = L ( i / EMF )
time = 2 * * 0.100 / 500
= 4 * seconds
