Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
