WebbNewton’s First Law Worksheet SOLUTIONS 1. Fully and clearly state Newton’s 1st law. An object in motion at a constant velocity (or at rest) will remain in motion at a constant … WebbThis problem deals with forces and acceleration, which suggests we should apply Newton's Second Law. To apply Newton's Second Law we draw a freebody diagram (FBD). In the … how to save a video from media player

WebbNumerical Problems 1. A force of 50N act on the object of mass 20 kg. shown in the figure. Calculate the acceleration of the object in x and y directions. Ans: ax=2.165 ms-2; ay=1.25 ms-2 2. A spider of mass 50 g is hanging on a string of a cob web as shown in the figure. What is the tension in the string? Answer: T = mg Mass (m) = 50g = 0.050 kg WebbThe Normal force N is easy, by inspection: N_x=0, and N_y=+N. The weight W is trickier. Here I redraw the weight vector. The important (critical!) thing is to convince yourself … WebbNewton’s third law means the Force is acting on the balls, but also on the feet doing the kicking.
