A person hold the end of a rope with a ball on its other end and spin in a circle (so the ball is moving in a completely horizontal circle). The ball has a mass of 2.00kg, their mass is 50.00kg, the distance from the center of the ball to the center of their body is 1.00m, and it takes 2.00 s for them to make one full turn. The rope breaks as you are spinning and the ball flies off. After it flies out of the circle, the ball hits the ground, having a completely horizontal velocity of 1.00m/s as it hits the ground. It then skids completely horizontally on the ground for 10.00s until it is brought to a complete stop by the friction with the ground. The work that the ground friction does on the ball to stop it is:

a. infinity

b. positive

c. 0 J

d. negative
