The velocity of a 150 gram ball changes from < 10, −5, 0 > m/s to < 10.2, −5.6, 0 > m/s in 0.07 s, due to the gravitational attraction of the Earth and to air resistance.

a. What is the acceleration of the ball?
b. What is the rate of change of momentum of the ball?
c. What is the net force acting on the ball?

prolly a beacuse the momentuem the car has increases while going down hill

  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

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
