The distance traveled per unit time is called speed.
Hope this helps you!
The first thing you should know is that the work is defined as:
W = F * d
Where
F = force
d = displacement
We have then
(a) the block
F = (0.2) * (100) = 20
d = 100
W = (20) * (100) = 2000 ft.lbf
(b) the man as the system.
F = (0.2) * (100 + 180) = 56
d = 100
W = (56) * (100) = 5600 ft.lbf
answer:
(a) 2000 ft.lbf
(b) 5600 ft.lbf
Answer:
When Jill is pushing a box across a floor, it represents the upward motion and it is natural force is applied.
So it is represented as FN and normal force takes place in considering the force perpendicular to the floor.
It seems to support that forced applied on an object when the object is in contact with other.
Explanation:
Answer:
Yes it does
Explanation:
Gravity is pushing down on the pencil but the coffee mug is also pushing the pencil up with the same amount of force so they both don't move
C I’m not that sure though
