A ball is launched at a 58 degree angle to the horizon with a velocity of $28\mathrm{m}/\mathrm{s}$. Ignoring air resistance, at what other angle (between 0 and 90 degrees) can the ball be launched and travel approximately the same horizontal distance? $?=\text{ degrees }$ Ignoring air resistance, what is the magnitude of the velocity that the ball will hit the ground with? $v=$ unit
