A multiflash photograph of a ball is being shot straight up by a spring. The spring, with the ball atop, was initially compressed to the point marked Yแตฆโ‚’โ‚œ and released. The point marked Yแตฆโ‚’โ‚œ is the point where the ball would remain at rest if it were placed gently on the spring, and the ball reaches its highest point at the point marked Yโ‚œโ‚’โ‚š.For most situations, the point Yโ‚€ may be taken to be at the top of the spring, where the ball loses contact with the spring. Indicate whether the following statements are true or false. Assume that air resistance is negligible.1. The speed of the ball was greatest at point Yโ‚€ when it was still in contact with the spring.2. The speed of the ball was decreasing on its way from point Yโ‚€ to point Yโ‚œโ‚’โ‚š.3. The speed of the ball was zero at point Yโ‚œโ‚’โ‚š.4. The speed of the ball was the same for all points in its motion between points Yโ‚€ and Yโ‚œโ‚’โ‚š.
