Question

A boy standing at the point O in the given diagram throws a ball three times with the same force, but projecting it along different inclinations from the ground. The results of the throws have been plotted in the diagram. Which one of the following is a valid conclusion?

(a) The larger the initial inclination, the longer the throw 

(b) The larger the height reached, the longer the throw 

(c) The larger the height reached, the shorter the throw 

(d) The larger the initial inclination, the greater the height reached

Answer 1

(d) The above diagram represents a body in projectile motion

Maximum height y_max =v²sin²θ/2g 

Thus, according to above equation greater the initial inclination, the greater is the height reached.
