1. What is the average force exerted by a shot-putter on a 7.0 kilogram shot if the shot is moved through a distance of 2.8 meters and is released with a speed of 13 m/s? 2. F=ma, x = vo t + 1/2 at^2, v=vo at 3. I think you get time by using D = vt, but when I use this time and plug it into the distance equation above I get a weird answer. The real answer should be in the ballpark of 200 Newtons.
