An object moving with a speed of 67 m/s and has a kinetic energy of 500j , what is the mass of the object

0.223kg

Explanation:

Kinetic energy is the energy possessed by a body by virtue of its motion. Mathematically,

Kinetic energy = 1/2MV² where;

M is the mass of the object

V is the speed of the object

Given speed = 67m/s

Kinetic energy = 500Joules

Mass = ?

To get the mass, we will substitute the value given into the kinetic energy formula to have;

500 = 1/2M(67)²

500 = 2244.5M

M = 500/2244.5

M = 0.223kg

Therefore, the mass of the object is 0.233kg

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

heat the gas and measure the pressure
