In a "RamLeela"stage show an unhappy guy from audience throws an rotten egg at Rawana. The egg travels a horizontal distance of 15 m in 0.75 s before hitting the Rawana's face 1.7 m above the stage. The egg is thrown at 2.0 m above the horizonta floor with an initial velocity `30^(@)` above the horizontal, (a)Find the initial and final velocities of egg. (b)How high is the stage above the floor. Take `g = 10 m//s^(2)`

Answer

[(a) `(40)/(sqrt3)m//s, 20.40 m//s` (b) 6.15 m]
