Answer:
0 N
Explanation:
suppose, you push a box with 5 N, and another person pushes the box on the opposite side of the box with 5 N, the net force (resultant ) is 0 N, the box will not move if it wasn't moving
hope this helps
To calculate the momentum, you have to use the equation p=mv or p to mass times velocity.
Answer:
KE = 1/2 * m * ![v^{2}](https://tex.z-dn.net/?f=v%5E%7B2%7D)
Explanation:
use the formula:
KE = 1/2 * m * ![v^{2}](https://tex.z-dn.net/?f=v%5E%7B2%7D)
KE = kinetic energy in joules (J)
m = mass in kg
v = velocity in m/s
I'm not sure I completely understand the expression you want evaluated.
It looks like a fraction with the same exact thing in both the numerator and the denominator. A fraction like that always boils down to ' 1 '.
