Hi Texasgirl03, Take a look a the diagram and see if it makes the problem any clearer. Notice that there's two forces acting upwards the Normal force (N) & the y component of the 150N force (Ty), and one force pulling downwards (Fg). Find Ty and remember that according to Newton's Second Law...

Hi elkosp16, you need to use the formula : Δ X = Vi*T + (1/2)*a*T^2 You already know displacement (ΔX), 85 cm (remember to convert it to meters !) Initial velocity (Vi) is 0, because it starts at rest. Time = .50 seconds, Plug everything in and solve for a, once you get acceleration, use...
