The answer is 1014. Look at my work...
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.

Answer:
∠U = 60°
∠W = 30°
Step-by-step explanation:
The side length ratios are ...
1 : √3 : 2
so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).
The angle measures are ...
m∠U = 60°
m∠W = 30°
[the UW measure is correct]

<em>Additional comment</em>
Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
2000 is the nearest 10 thousand
