Answer:
Explanation:
The distance equation is normally d = v0*t + .5at^2 with a of course being the acceleration due to gravity, so -32 ft/s^2. The problem gives us v0, but also tells us we are already starting 117 feet, so we want to add a 117 to that. so d = v0*t + .5at^2 + 117. And this is in terms of t so that's what is asked for.
If you need extra help finding the maximum let me know, but completeing the square can get you the vertex form which makes finding the maximum very easy.
If you set it equal to 499 and solve for t it will get you the two times that it is at 499 feet, and that will get you the time interval.
If you simply set it to 0 it will get you the two times when the function equals 0, one should be positive and the other negative, since you can't go into negative time the positive one will be when it hits the ground.
Again, let me know if you need help carrying out these calculations and I'll be happy to walk you through them.

Explanation:
s = ut + 1/2 a t^2
375 = 0 * 5 + 1/2 * a * (5)^2
375 = 1/2 * a * 25
a = 375*2/25
a = 15* 2
a = 30m/sec^2
v = u + at
v = 0 + 30 * 5
v = 150 m/sec
hope it helps you
Answer:
1. The equivalent resistance for the combination of resistors in series is equal to the algebraic sum of all its individual resistances.
2. The Current will increase and causes it to have less restriction.
Explanation:
I did the Exam and made a 100% with these answers.
Hope this Helps!!!
Momentum = mass • velocity
M = m • v
Speed is a scalar quantity
Velocity is a vector quantity
That is truly the only difference
