Question

work out the kinetic energy of a 2.5kg remote-controlled car that is moving at 2m/s

Answer 1

Answer:

Answer: 5 joules

Explanation:

mass=m=2.5kg

Velocity=v=2m/s

Kinetic energy=ke

ke=(m x v x v)/2

ke=(2.5 x 2 x 2)/2

Ke=10/2

Ke=5

Kinetic energy=5 joules

Answer 2

Answer:

Explanation:

Mass of object (m) = 2.5 kg

Speed of object (v) = 2 m/s

As we know that ,

The amount of energy stored in an object due to its motion is called kinetic energy

Kinetic energy = (1/2) mv²

The SI unit of kinetic energy is joule
