. Calculate the kinetic energy of a 0.25-kg toy car traveling at a
constant velocity of 2 m/s.

See the attachment....

The kinetic energy of the toy car is 0.50 Joules.

Given the following data:

Mass of toy car = 0.25 kg Velocity = 2 m/s.

To find the kinetic energy of the toy car:

Kinetic energy is an energy that is possessed by a physical object or body due to its motion.

Mathematically, kinetic energy is calculated by using the formula;

Where:

K.E is the kinetic energy. M is the mass of an object. V is the velocity of an object.

Substituting the given parameters into the formula, we have;

K.E = 0.50 Joules

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
