The position of the particle is given by:
x(t) = t³ - 12t² + 21t - 9
Differentiate x(t) with respect to t to find the velocity x'(t):
x'(t) = 3t² - 24t + 21
Differentiate x'(t) with respect to t to find the acceleration x''(t):
x''(t) = 6t - 24
Answer:
20 ft
Explanation:
This is the length where the direct contact could be used as ground electrode
The correct answer is: Average Power = 500 W
Explanation:
Root-mean square voltage = Vrms = Vpeak /√2 = 100 / √2 volts
Resistance = R = 10 Ω
Average power = Pavg = (Vrms)^2<span> / R </span>= (100 * 100) / (2 * 10) = <span>500 W</span>
Answer:
1
The arrow with greater impart is Arrow B
2
The both arrows will feel the same impulse
Explanation:
1. Arrow B since 
it used more force to stop itself in a shorter distance.
2. They should feel the same impulse since the both had the same momentum 
Answer:
4. All of the above I think, not to sure about 1. but the rest are right so im like 90.99999 percent sure good luck
