A ball is thrown upward and caught when it comes back down. Neglecting air resistance, the speed with which the ball is caught is

A stone is thrown at an angle of 30 degrees above the horizontal. As it rises, its vertical component of velocity

If you drop an object, it will accelerate downward at a rate of 9.8 m/s2. If you instead throw it upward, its acceleration (in the absence of air resistance) will be
