Unformatted text preview: t (angle = θ) 2/17/2014 PHYS- 2010 10 How large a net force will you feel down the slope? What is the accelera>on down the slope? How fast will you be going a^er traveling down the slope for some >me t? Step 1: Draw a free- body diagram Note: “Normal Force” is always perpendicular (i.e. normal) to the surface of contact. Fg = mg 2/17/2014 In this case, it is not in the opposite direc>on to the gravita>onal force. PHYS- 2010 11 Step 2: Choose a coordinate system Fg = mg y y 2/17/2014 x x We could choose our “usual” axes… However, we know that we will have mo>on in both the x and y direc>ons. If we pick these rotated axes, we know that the accelera>on along y must be zero. PHYS- 2010 12 Step 3: Write down the equa>ons Σ Fx...
