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 Newton’s 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...
