The kinetic energy of an object can be determined using the equation , where is the kinetic energy, is the mass, and is the speed of the object. What is the mass of an object moving at a speed of 12 that has 36 J of kinetic energy?

0.5kg

Explanation:

Given parameters:

Speed of the object  = 12m/s

Kinetic energy  = 36J

Unknown:

Mass of the object  = ?

Solution:

Kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;

     K.E = m v²  

 Insert the parameters and solve;

    36  =   x m x 12²

     36  = 72m

       m  = 0.5kg

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
