Unformatted text preview: PYYS114 Practice Test #2 Page 1 of 6 [1] A 1.0kg physics book is given an initial velocity of 3.0 m/s up a ramp. The ramp makes an angle of 20 above the horizontal. If the coefficient of kinetic friction between the book and the surface is 0.2, how far up the ramp does the book slide? MODEL:( what assumptions are you going to make ?) VISUALIZE: Pictorial ( sketch with coordinate axis, and all symbols, list of knowns and unknowns ) Physical ( motion diagram ) Physical ( Free Body Diagram ) Page 2 of 6 Practice Test #2 PHYS114 SOLVE: ( use Newtons 2 nd Law for x and y and equations of motion to find the answer ) ASSESS: ( compare your acceleration to g and justify your distance is reasonable. 1.0 m/s = 2.24 mph ) PYYS114 Practice Test #2 Page 3 of 6 [2] You are playing a video game where the objective is to successfully fly a spaceship into a docking bay...
