1.The direction of an object's velocity changes uniformly from due east to due north. What is the direction of the acceleration? Explain/justify your reasoning. Note: "due" means directly. 2. Compare the vertical and horizontal components of velocity for a ball launched at an angle on a level surface. How do the vertical and horizontal components of the ball's velocities change as it travels through the air?

3.A Gr. 12 physics student on a homemade hovercraft travels with an initial velocity of 1.45 m/s [E20°N] undergoes an average acceleration of 2.10 m/s2 [S] for 2.5 s. What is the displacement?
