Answer:

Phasor

Explanation:

A phasor is usually referred to as a rotating vector which has scaled lines. A vector quantity is one which has both magnitude and direction.

Since a phasor is also a vector quantity it has the magnitude and direction in the form of quantity and displacement. The quantity and displacement are usually measured in a counterclockwise direction.

Phasors is used in the engineering world to establish relationships between AC quantities and the parameters such as current and voltage etc.

  • K.E=18750J
  • Mass=m=2100kg
  • Velocity=v

\boxed{\sf K.E=\dfrac{1}{2}mv^2}

\\ \sf\longmapsto 18750=\dfrac{1}{2}2100v^2

\\ \sf\longmapsto 18750=1050v^2

\\ \sf\longmapsto v^2=\dfrac{18750}{1050}

\\ \sf\longmapsto v^2=17.85m^2

\\ \sf\longmapsto v=\sqrt{17.85}

\\ \sf\longmapsto v=4.1m/s

A force gives a 2.0 kg mass an acceleration of 5.0 m/s2 on a level surface. What is the force applied to the mass?
Verdich [7]
So you can use the equation force = mass x acceleration to do 2 x 5 to get 10 N
