Because the information cant be out of the investigation
Answer:
if you need an actual number answer you can use :Vf = Vi + at. If you throw the ball it will have an initial force beside gravity accelerating the fall temporarily from greater than throw it downwards, its acceleration (in the absence of air resistance) will be greater than 9.8 m/s2 until it slows back down to a constant 9.8 m/s2 after ( t )amount of time
Explanation:
If you drop a ball, it accelerates downward at 9.8 m/s2. if instead you throw the ball straight downwards While throwing, we apply an additional force other than the gravitational force.
This gives an additional, temporary acceleration along with the gravitational acceleration.
Thus from the instant it is thrown and the instant it leaves your hand, the object is under variable acceleration, the variation of acceleration being the reason of the varying force which we do apply on the object. But once it leaves our hand it is always under constant acceleration of g which is9.8 m/s2
a=advantage of the machine
f1=force that is applied
f2=force the machine applied
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
