Problem 3: I start walking. The 1" leg of my trip I walk da - 85 m at GA - 130 south of east. The 2nd leg of my trip I walk de " 115 m at Op - 250 north of east. On my final leg I walk de - 95 m at ec # 50.5" north of west. Choose the coordinate system so that x is directed towards the east, and y is directed towards the north. Part (a) Write an expression for the x-component of the final displacement in terms of the given quantities. Expression Select from the variables below to write your expression. Note that all variables may not be required. cos(a). cos(). cos(0), cos(0A). cos(0B). cos(0c). sin(a). sin(), sin(0), sin(0). sin(0p). sin(0c). dA. dg, dc Part (b) Write an expression for the y-component of the final displacement in terms of the given quantities. Expression Select from the variables below to write your expression. Note that all variables may not be required. cos(a), cos(p), cos(0), cos(0). cos(0B), cos(0c). sin(a). sin(), sin(0), sin(0A). sin(0g). sin(0c). dA. dg, dc Part (c) What is the magnitude of my displacement vector (in meters) as measured from the origin? Numeric : A numeric value is expected and not an expression. R Part (d) What is the angle of my displacement vector as measured counterclockwise from the +x-axis? Numeric : A numeric value is expected and not an expression. OR
