- A 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…P3C A hiker takes a three - part journey as described in map coordinates below.
