You are trying to find out how high you have to pitch a water balloon in order for it to burst
when it hits the ground. You discover that
the balloon bursts when you have pitched it
to a height of 18 m.
With what velocity did the balloon hit
the ground? The acceleration of gravity is
9.8 m/s². The positive direction is up, so the
velocity when it hits is negative.
Answer in units of m/s.

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
