(1) A stone is thrown obliquely upwards with the output speed 25m / s from a point 1.5m above ground level. The throwing height of the bow is 26.0m above the ground. how big is the stone's speed when it passes the highest point? we ignore the air resistance.

As a stone is thrown obliquely upward horizontal component of velocity is zero. When the stone passes the highest point its kinetic energy is zero. Thus, the stone's speed is zero:
