Linearly N6: Constrained Motion Problem: A box of mass m slides down an inclined plane that makes an angle with the horizontal. The coefcient of sliding friction between the box and the plane is . What is the acceleration of the box? Concept Test A physics student attaches skateboard wheels to the bottom of a bathroom scale and rolls down a 30 slope. Neglecting friction and air resistance, the scale reading is 1. his normal weight. 2. cos(30) times normal his weight 3. sin(30) times his normal weight 4. none of the above Problem: A box of mass m is being pulled along a horizontal surface by a rope that can withstand a maximum tension T. The coefcient of kinetic friction between the box and the ground is . What is the maximum acceleration of the box? Problem: If someone drops a penny from the Empire State Building and it hits a pedestrian, will it kill them? Do not ignore air resitance!
