Vertical forces:
There is a force of 579N acting upward, and a force of 579N
acting downward.
The vertical forces are balanced ... they add up to zero ...
so there's no vertical acceleration.
Not up, not down.
Horizontal forces:
There is a force of 487N acting to the left, and a force of 632N
acting to the right.
The net horizontal force is
(487-left + 632-right) - (632-right - 487-right) = 145N to the right.
The net force on the car is all to the right.
The car accelerates to the right.
Answer:
A) F=650N
B) W=0J
C)
Explanation:
A) Considering the equation , we can calculate:
B) The work the wall does is 0J, because the fingers of the scater against it do not move. It's the muscles on his arm that do the work.
C)
Answer:
I looked it up but got perihelion so I don't know if that will help at all but try um.... I don't know try L
Explanation:
Use acceleration = Final Velocity - Initial Velocity. So for the first one:
1.6m/s - 3.6m/s = -2.6m/s. This means the velocity changed by a negative amount so the acceleration is negative.
