A 0.964 kg radio-controlled car is driving 4.38 m/s. What is its momentum?

Unit: kg*m/s

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

** 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

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
