QUESTION 4 Choose a coordinate system with origin at the motion sensor and X-axis parallel to the track, with x increasing away from the motion sensor Assume that the cart is initially positioned on the track at x>0. If the cart moves along the track with initial speed Vo towards the motion sensor, which equation describes its motion from the time it starts to move until it returns to the initial position? (Assume that there is no friction or air resistance and that the cart does not hit the motion sensor.) OA x = xo + vot + (a sin e) +² OBX Xo-Vot + of +/(a sin 0) 1² OC.x = xo + vot - Dix-xo-Vot - (0 sin 8) 1² (g sin 6) 1² QUESTION 5 Using the assumptions of the previous question, which equation described the velocity of the cart from the time it starts to move until the time it returns to its initial position? OAV=Vo OB.V=-Vo OC.v=vo+(g sin 8) t OD.V-Vo+(g sin 8) t E.V=-vo-(g sin e) t
