Explanation:
Why do your lights actually come on almost instantaneously? ... Wiring the house in parallel does not make a difference – there is no current flowing through the light bulb when the switch is off no matter how the house is wired. If there were a current already, the light would be on!
Answer:
8.9m/s
Explanation:
Final velocity = initial velocity + acceleration *time
Vf=vi+at
Vf=1.4 m/s
Vi=?
A=-2.5m/s^2
T=3
1.4m/s=vi+(-2.5m/s^2)(3s)
Vi=8.9m/s
Here are the steps you would need to follow:
#1). Define what 'the 'X is, and how it's related to the ball.
#2). Be clear on how 'the X' is related to the 'known velocity'.
#3). Identify how the 'known velocity' is related to the action of the ball when it's launched.
With this information in front of you, you'll have a much better chance
of answering the question.
With none of it in front of me, I have no chance at all.
