A climber pulls down on a rope causing his body to rise up with the rope? Which law of motion is it?
12345 [234]
This would be called the law of action-reaction. This states that every action will have an equal and opposite reaction. The action in the example is pulling down on the rope. The opposite and equal reaction is the climers body moving upward. The same law can be applied to a rocket. The action is the engines pushing down and the reaction is the rocket going up. :D

Find the power of a force F~ = (8 N)ˆı + (−4 N) ˆ if the velocity ~v = (−7 m/s)ˆı + (1 m/s) ˆ. Answer in units of W
Vikki [24]

Answer:

P=-60W

Explanation:

From the question we are told that

Force of power F=8Ni+-4Nj

Velocity of power V=-7m/si+1m/sj

Generally the equation for power is mathematically represented as

Power=Force *Velocity

P=F *V

Generally the dot product of F and V is mathematically given as

P= \begin{vmatrix}8 & -4\end{vmatrix} .\begin{vmatrix}-7 & 1\end{vmatrix}  =-56-4

P=-60W
