- Suppose you walk 87 m to the north, stop and turn to your right through an angle of 42.1°, and then walk in that direction another 76.2 m. Find the direction of the vector extending from your starting to your ending location. Express your answer as an angle relative to east. 0 N of E Report your numerical answer below, assuming three significant figures, DA man pushing a mop across a floor causes it to undergo two displacements. The first has a magnitude of positive x axis. The resultant displacement has a magnitude of R = 138 cm and is directed at an angle of direction of the second displacement. Step 1 The diagram suggests that d, is larger than either of the other vectors and is in a fourth-quadrant direction. 2 d₁ Then d₂ = R-d₁ 1 Substituting, d 2 y Step 2 We will use the component method for a precise answer. We already know the resultant displacement, so the algebra of solving a vector equation will guide us to do a subtraction. Step 3 The resultant displacement of the mop is R = ď₁ + 1 2 = = 19₂ R (138 138 cm at 33.0°) - 157 Step 4 The meaning of the negative sign reverses the direction of the second vector so we can rewrite the previous equation as (138 cm at 33.0°) + (157 cm at 33 X The response you submitted has the wrong sign.º), which, in components, is d₂ = [138 cos 33 + 138 sin 125 Your response..differs from the correct…C please
