MIME 2300 Test 1 Retest Name _______________________ Section ______ February 26, 2007 In all the problems show all equations used with variables and then with values substituted so partial credit can be given wherever possible. Give units on all answer. On problems where appropriate, draw coordinate systems, datums, FBDs, K.Ds or velocity diagrams. 1. A projectile is launched at 10 m/s from a sloping surface. The equation of the surface is 3 L L x y - = as shown. Determine the coordinates of the point of impact, x L and y L .
