A ball is throw into the sky at 18m/s. How high can it reach?

The maximum height of the ball will be "16.53 m".

Explanation:

Given that,

As we know,

The initial as well the final height on the ball will be same after it reaches it's maximum height.

then,

⇒

where,

hence,

The max height of the ball will be:

⇒

f is prop to m1xm2 double m1 double force

  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
