thank you! now I can at least breath a little easier. the question for the first was pretty simple. a force is applied at 20 degrees relative to the horizontal on a 2kg object. The object follows a parabolic trajectory. What is the magnitude of the force acting on the object at the top its...

1. a force is directed 20 degrees from the horizontal on a 2kg object. At the top of its projectory, what is the magnitude of the force acting on the object. I said 19.6 N, because the only force acting there would be gravity, right? so 9.8*2 = 19.6 N 2. an object that weighs 3m explodes...
