Answer:
Explanation:
if you are pulling in the positive direction and Upward is also positive.
F = -0.96i + 0.58(9.8)j
F = -0.96i + 5.7j
F = √(-0.96² + 5.7²) = 5.8 N
Answer:
Newton states his second law of motion in terms of momentum: The net external force equals the change in momentum of a system divided by the time over which it changes or F = m*a. The change in momentum is the difference between the final and initial values of momentum. ... It is equal to the change in momentum.
Explanation:
Resistor 1 and three are in series so the total resistance is 1.
Momentum is a vector, although we don't hammer on that. In order to completely describe a momentum, you need a magnitude AND a direction ... just like force and velocity.
So choice #2 is the magnitude of a momentum, without its direction.
<em>Choice #3</em> is the full package, with both the magnitude and the direction.
Choice #1 has units of energy, and choice #4 has units of acceleration, so neither of those can be it.
