1. A ball is thrown into the air from an initial height of 10 feet. Its height above the ground, in feet, t seconds after it is thrown is given by the function h(t) = -16t +27t + 10. How long will it take (in seconds) for the ball to hit the ground after it is thrown?
A ball is thrown straight up into the air. At the highest point of its trajectory, what is its velocity?相关知识点: 试题来源: 解析 0 当物体被垂直向上抛出时,其速度会因重力加速度持续减小。在轨迹的最高点,物体在竖直方向上的速度变为零,此时重力加速度开始使其加速下落。因此,在最高点的瞬时...
