During batting practice, a 0.30-kg baseball is hit with a bat that exerts a force of -350 N on the ball. The ball left the bat at -80. m/s. If the incoming pitch was traveling at 60. m/s, how long did the ball stay in contact with the bat? 0.50 s

1.4 s

0.12 s

0.85 s

  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

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
