I. Fig. 4: Projectile Motion IV Suppose that the motion of the projectile shown in the figure above is ideal without friction. Choose the correct statements on the motion in 1 and 2 below for this assumption. 1. (a) The value of vx is continuously positive and decreases only marginally over time. (b) The value of Vx varies from positive to negative over time. (c) The value of v, is always negative and increases marginally over time. (d) The value of Vx is still positive and constant over time. (e) The value of vx varies from negative to positive over time. 2. (a) The value of vy is still positive and decreases only marginally over time. (b) The value of vy is changed from positive to negative over time. (c) The value of v, is always negative and increases only slowly over time. (d) The value of vy is still positive and constant over time. (e) The value of vy is changed from negative to positive over time.
