Abat hits a 0.150 kg baseball for
0.0930 s. the ball's velocity
changes from 47.0 m/s left to
32.0 m/s right. what impulse was
given to the ball?
(unit = kg*m/s)
remember: right is +, left is -

11.85 kg m/s

Explanation:

impulse = mass ( change in velocity )

              = mass ( final velocity - initial velocity )

               = 0.150 ( 32.0 - (-47.0))

                = 0.150 ( 32.0 +47.0)

                = 0.150 (79)

                = 11.85 kg m/s

we need to know the time interval during which the force acts. impulse of force = momentum change

  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
