1 Problem During a particularly snowy winter in Charlotte, a child of mass m slides down a ramp starting at rest from point A and encounters the melted grassy area at B before coming to a full stop at C. Assume the ice is frictionless. The height of point A is hĄ and the distance between B and C is L. What is the coefficient of friction of the grass, k? Assume that g = 9.81 m/s², ha = 5 m, m = 20 kg, and L = 10 m. hA P JA Ice B Grass L C
In the situation illustrated in the figure below, a small package is deposited by a conveyor belt at point A onto a ramp at theta = 35 degrees degrees to the horizontal with a velocity of 0.5m / s . The distance between points A and Bis 2 m. a)Calculate the maximum value mu k ^ * of the kinetic friction coefficient between the package and the ramp AB for which the parcel reaches point B. b) If the actual kinetic friction coefficient between the package and AB and BCis mu k =0.5 mu k ^ * calculate the distances on the level surface BC at which the package comes to rest. Note: if you haven't been able to solve part a), take the actual kinetic friction coefficient equal to mu_{k} = 0.28

Dynamics
Consider a projectile launched at a height h feet above the ground and at an angle ? with the horizontal. If the initial velocity is v0 feet per second, the path of the projectile is modeled by the parametric equations x = t(v0 cos(?)) and y = h + (v0 sin ?)t - 16t2.Let h=6, v0=63.25, and ?=0.79. Find the maximum height of the projectile. (Round your answers to two decimal places.)
