Kinetic energy is the energy an object has as a result of its

Explanation:

The kinetic energy of an object is given by due to its motion. Mathematically, it is given by :

Where

m = mass of an object

v = velocity

The kinetic energy of an object depends on its mass and the velocity with which it is moving. So, basically kinetic energy of an object depends on its motion.                            

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
