Answer:
range becomes 4 times
Explanation:
We know that the range of a projectile is given as:
where:
range of the projectile
initial velocity of projectile
initial angle of projection form the horizontal
g = acceleration due to gravity
When the initial velocity of launch is doubled:
range becomes 4 times
I do not recall the answer to this question
You have to be aware of what Newton's laws where, Newton had three laws here's a picture to help you see his three laws, hopefully this will help you
This is easy if you know the speed of sound through water. That speed depends
on the temperature of the water, but in the range of temperatures in which you'd
want to be out fishing, it's around 1,480 meters per second.
So, in 2 seconds, sound travels (2 x 1,480) = 2,960 meters, in water.
But the sound has to go down and back up before the boat hears it, so the
actual depth of the water is only half of that distance.
1/2 of 2,960 meters = <u>1,480 meters deep</u>
