解释一下这道题---**Question Number:** 10 **Question Stem:** 如图所示，一个 [小球] 在离地一定高度处以大小为 $v_0$ 的速度水平向右抛出。在小球运动过程 [中] 一阵风从左向右沿水平方向吹来，使小球受到一个水平向右大小恒定的风力，风力作用时 [间] 为小球下落时间的二分之一。不计空气阻力，则风力作用时间越早... (As shown in the figure, a [small ball] is thrown horizontally to the right at a certain height above the ground with a speed of $v_0$. During the movement of the small ball, a gust of wind blows from left to right along the horizontal direction, causing the small ball to receive a constant horizontal force from the wind to the right. The duration of the wind force is one half of the ball's falling time. Ignoring air resistance, then the earlier the wind force acts...) **Options:** A. 风力的冲量越大 (The greater the impulse of the wind force) B. 小球落地时的速度越大 (The greater the velocity of the small ball when it lands) C. 风力对小球做功一样多 (The work done by the wind force on the small ball is the same) D. 小球在空中运动的水平位移越大 (The greater the horizontal displacement of the small ball during its motion in the air) **Chart/Diagram Description:** * **Type:** Schematic diagram illustrating projectile motion with an additional horizontal force (wind). * **Elements:** * A starting point (represented by a circle). * An arrow pointing right from the starting point labeled $v_0$ (initial horizontal velocity). * An arrow pointing downwards from the starting point (representing gravity). * A curved line starting from the initial point and curving downwards and to the right (representing the trajectory). * Three parallel arrows pointing to the right, labeled "风" (Wind), representing the horizontal wind force. * A horizontal line with zigzag hatching below it, representing the ground. * A dashed vertical arrow pointing from the starting point to the ground (representing the vertical displacement or height). **Other Relevant Text/Annotations:** * Handwritten text "AB" and "CD" near the question number. * A circle around option B. * Handwritten text "一定" (certain/fixed) next to option A. * Some illegible handwritten symbols or text near options B and C.
