What is the kinetic energy of a 0.500 kg toy car moving at a rate of 1.50 m/s

0.5625 J

Explanation:

To calculate the kinetic energy of bodies, use the following equation:

Ec = (m.v ^ 2) / 2

Where:

Ec: kinetic energy can also be represented by the letter K (J).

m: body mass (kg)

v: body speed (m / s)

From this it is concluded that if we double the mass of a body while maintaining its velocity, its kinetic energy will also double.

On the other hand, velocity is squared, so if its value doubles and its mass remains constant, the kinetic energy will be quadrupled.

We can then calculate the kinetic energy of the toy car as follows:

Ec= (0.500 x 1.50^2) / 2

Ec= (0.500 x 2.25)/2

Ec=  1.125/2

Ec= 0.5625 J

google my dude. if it doesn't show up ask me.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
