An unknown force is applied to a 12 kg. the force acts at an angle of 30 degrees above the horizontal. determine the force acting if the force acts for a horizontal displacement of 22 meters and increases the 12 kg mass's speed from 11 m/s to 26 m/s

Time it take to displace to 22 m :

D     =  0.5 (Vi-Vf) t
22m = 0.5  ( 11+ 26)t
      t = 1.189 s

Acceleration

22m    = vt + 0.5at^2
a         = 12.616 m/s^2

F = ma

F sin 30 = 12 kg x 12.616 m/s^2

F = 302.805 N

 

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
