5. A raindrop falls on a slanted roof 5.5 m/s and rebounds off with a velocity of 5.5 m/s at an angle 60 with respect to the horizontal as shown in the following 60 figure. The maximum horizontal distance roof travelled by the raindrop is 4.4 m. Calculate the speed of the raindrop when it hits the ground. Assume that air resistance is negligible. Approximate the raindrop as a projectile. (11.26 m/s)
