Problem

A golfer hits a shot up a slope of

30^{\circ}

with an initial speed of

50\,\text{m/s}

. The ball is launched at an angle of

30^{\circ}

relative to the slope surface. Calculate the time at which the ball is at its maximum perpendicular distance from the slope surface. (Take

g = 10\,\text{m/s}^{2}

)
