The net force is force applied + force friction ( which is negative ) Unfortunately for some reason the numbers are negative, could you ask your teach about that?
Btw, left is usually force fric. which makes it negative
(-750+-250+-550)+1563 = net force
(-792+-632+-100)+(400+900) = net force
(m.v^2)/2
(5,97x10^24 x 461^2)/2
= 6,34x10^29
Answer:
300N
Explanation:
If both people push the box in the same direction the force applied to the box is the sum of the N from both peoplef:
100N + 200N = 300N
Answer:
The average power the student expended to overcome gravity is 560W, Watts is a units of work it is Joules /time or kg*
/ 
Explanation:
Weight = 700N

The power is the work in (Joules) or (N*m) in a determinate time (s) to get Watts (W) units for work

C.) Pedestrians yielding to cross traffic.
