A fooball is kicked off with an initial velocity of 64 ft/s at an angle of 45 degree. A goal-keeper at the goal-line, 180 ft away in the direction of hit, starts running uniformly to catch the ball at that instant. What must his speed be if he runs with uniform speed to catch the ball just before it hits the ground?
[Given - g = 32 ft/s^2]
