Answer:
8i
Step-by-step explanation:
<em>When a quantity is raised to a fractional power, you need to root it to the power of the denominator. </em>
<em>For example, </em><em>(-64)^(1/2) = √(-64) </em>
<em>Since you are taking the root of a negative, you will need to put an </em><em>i</em><em> (imaginary) in your answer.</em>
Answer:
-2 m/s^2
Step-by-step explanation:
Just as you would calculate the velocity when a body moves from point A to point B in a time T, we are going to calculate the acceleration as the difference of the velocities (final - initial) and divide it by the time it took:
Velocity_final = 10 m/s
Velocity_initial = 20 m/s
Time = 5 s
acceleration = (Velocity_final - Velocity_inital)/Time
= (10 m/s - 20 m/s)/5 s
= (-10 m/s) / 5s
= -2 m/s^2
The acceleration in m/s^2 is -2
Using the Law of Cosines:
d= √(840^2 + 800^2 - 2*840*800*cos(105))
d = √1693452.796
d = 1301 miles.
The answer is B.
