The velocity of a ball changes from ‹ 9, −6, 0 › m/s to ‹ 8.96, −6.12, 0 › m/s in 0.02 s, due to the gravitational attraction of the Earth and to air resistance. The mass of the ball is 120 grams.

(a) What is the acceleration of the ball? a with arrow = Correct: Your answer is correct. (m/s)/s

(b) What is the rate of change of momentum of the ball? dp with arrow/dt = Incorrect: Your answer is incorrect. (kg · m/s)/s

(c) What is the net force acting on the ball? F with arrownet = N
