A ball weighing 300 g is thrown at an angle of 60 ° to the horizon with an initial velocity of v = 20 m / s. The modulus of gravity acting on the ball at the upper point of the trajectory is equal to:

choosing tennis and golf balls is your inde choice.

  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
