Use the kinetic energy formula KE = 0.5 mv2to complete the practice problems below. Remember, 1 J = 1 kg m2s2Also, velocity is v2KE / (0.5 x m)and mass is m = KE / (0.5 x v2What is the kinetic energy of a 150 kg object that is moving at a speed of 15 m/s?

** urgent** the voltage across the primary winding is 350,000 v, and the voltage across the secondary winding is 17,500 v. if the secondary winding has 600 coils, how many coils are in the primary winding? a- 30 coilsb- 583 coilsc- 12,000 coilsd- 332,500 coils
