Questions
An object is thrown towards the tower which is at a horizontal distance of 50 m with an initial velocity of 10 ms-1 and making an angle 30° with the horizontal. The object hits the tower at certain height. The height from the bottom of the tower, where the object hits the tower is (Take, g = 10 ms-2)
detailed solution
Correct option is A
Consider the diagramFor horizontal motion, 50 = 10 cos 30° x t⇒ t=5cos30°=532=103For vertical motion,h=10sin30°×103-12×10×1032 =10×12×103-1003×53=100312-53 =5031-103mTalk to our academic expert!
