Learning Objectives: In this assignment students will use Newton’s laws and solvesystems of symbolic equations to find quantities of motion such as position, velocity,acceleration and time. Students will represent information in multiple ways. Studentswill make predictions and assess their work.Problem Statement: An object of mass m rests at the top of a smooth slope ofheight h, length L and angle ?. The coefficient of kinetic friction ??. A very smallpush overcomes static friction, and the object begins to slide down the slope.Using your knowledge of kinematics, determine a symbolic expression for the object’sspeed when it reaches the bottom of the hill. This should be in terms of some of all ofgiven/known variables m, h, L, g, ? and ??. Check the physical units of yourexpression.
