1 Draw a free body diagram of the block and cart (treated as a single mass) as soon as they leave the spring at the top of the ramp. Free body diagrams 1 0.5 0 Question 2 From Equation 7 in the lab instructions, derive an expression for the displacement of the block ( s ) down the slope. If you were to double the mass of the block and cart (treated as a single mass), what effect would this have on their displacement down the slope? Understanding of governing equations 1 0.5 0 Question 3 Draw a free body diagram of the block and red cart (treated as a single mass) when they are being pushed at a constant velocity on a horizontal track (described in Part B - Step 3 of the instructions). Free body diagrams 1 0.5 0 2 Question 4 Derive an expression for the ramp angle ( ) at which the block and red cart (treated as a single mass, m) will slide down the ramp at a constant velocity if the coefficient of kinetic friction between the block and ramp is given by k.
