Question 3: the position of a particle moving along the y-axis is given by: A ball is thrown from the ground at an angle of = 30. 0 above the horizontal towards a building that is. Question 6: an object moves around a horizontal table. Question 7: an object moves in the xy plane. At t = 0 s, the object is moving with a velocity ~vi. Ten seconds later, the object is moving with a velocity ~vf both velocity vectors are shown in the gure below. How long does it take to pull the box 3. 50 m across the oor if the box starts at rest? (a) 1. 33 s (b) 1. 76 s (c) 2. 11 s (d) 2. 98 s (e) 4. 44 s. Question 9: a box which weighs 25. 0 n is released from rest from the top of a rough plane that is inclined at an angle of 30. 0 above the horizontal.
