Answer:
The work done on the box is 69.28 ft-lb
Step-by-step explanation:
Work done = force × height
Force (F) = 10 pounds
The height (h) is calculated using trigonometric ratio
Length of ramp (hypotenuse side) = 8 feet
Angle of inclination above the horizontal = 30°
h/8 = cos 30°
h = 8cos 30° = 8×0.8660 = 6.928 feet
Work done = F×h = 10 pounds × 6.928 feet = 69.28 ft-lb
the redius is 0 unit or 1/2^(1/2) unit.
3/4
2/3= 0.6
1/8= 0.125
3/4= 0.75
<u>I convert the fractions into </u><u>decimals the decimal with the highest number in the tenths place is the biggest </u>
<u>Hope This Helps!</u>
