<span>The function of an electric motor is to change electrical energy
into kinetic energy.

Even if you want to use the electric motor to give a heavy weight
a lot of potential energy, by lifting it up onto, say, the roof of a house,
you still have to use the motor to MOVE the weight. So you're still
giving it kinetic energy as an intermediate step..

What is the magnitude of the force that is exerted on a 20 kg mass to give it an acceleration of 10.0

ANEK [815]

Answer:Mass of the body = 20 kg.

Final Velocity = 5.8 m/s.

Initial velocity = 0

Time = 3 seconds.

Using the Formula,

Acceleration = (v - u)/ t

= (5.8 - 0)/ 3

= 1.6 m /s².

Now, Using the Formula,

Force = mass × acceleration

= 20 × 1.6
