In which of the following situations would the least work have been done?
1 answer:
<span>
Work = (magnitude of the force) x (distance in the direction of the force)
A 100-N force lifts an object 3 m. ==> (100 x 3) = 300 joules
B. A 250-N force moves an object 1 m. ==> (250 x 1) = 250 joules
C. A 25-N force moves an object 8 m. ==> (25 x 8) = 200 joules
D. A 600-N force is applied to an object
and moves it 0 m. ==> (600 x 0) = no work
</span> Winner ! Least work.

Constant speed along the inclined surface = 30 m / 4 s = 7.5 m/s
Vertical speed = inclined speed * sin(45) = 7.5 *√2 / 2 = 5.3 m/s
Answer: 5.3 m/s
Average speed = total distance traveled/total time taken
it is the total distance traveled in a total time the total distance is attained
