Answer:
The answer to your question is the third option
Step-by-step explanation:
a) 0.023x³ + 0.4x² - 2.1x + 8.3
0.023(2)³ + 0.4(2)² - 2.1(2) + 8.3
0.023(8) + 0.4(4) - 2.1(2) + 8.3
0.184 + 1.6 - 4.2 + 8.3
10.084 - 4.2
5.884
b) 0.023(4)³ + 0.4(4)² - 2.1(4) + 8.3
0.023(64) + 0.4(16) - 8.4 + 8.3
1.472 + 6.4 - 8.4 + 8.3
16.172 - 8.4
7.772

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.
