Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied physical principles which are on the last page. 2 ayt 2 " y = 0 + (8. 00)(1. 50) # 1. 2 (9. 80)(1. 50) 2 (b)use the kinematic equation for y, y = yo + v oyt + 1. Finally, y = 0. 975m : a 95. 5n board is sandwiched between to other boards as shown. The coefficient of friction between the boards is 0. 663. (a)draw the forces that act on the 95. 5n board. (b)find the magnitude of each force. Fg = 95. 5n x n1 $ f n 2 x # f x = ma. "fy = may # f f 1 + f f 2 $ fg = 0. " f f1 + ff 2 = fg. Using the definition of cof, ff 1 = fn1 and ff 2 = fn 2 .
