When an unknown amount of force was exerted on a sled, the sleds velocity went from 0 to 9 m/s in 3 seconds. If the mass of the car is 10 kg, what must be the force applied?

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
