Question
Two identical balls are projected, one vertically up and the other at an angle of $30^{\circ}$ with the horizontal, withsame initial speed. The potential energy at the highest point is in the ratio(A) $4: 3$(B) $3: 4$(C) $4: 1$(D) $1: 4$
Step 1
The first ball is projected vertically upwards, so the maximum height it reaches, $H_1$, can be calculated using the equation $H_1 = \frac{u^2}{2g}$, where $g$ is the acceleration due to gravity. Show more…

"Two balls of same mass are projected one vertically upwards and the other at angle 60o with the vertical. The ratio of their potential energy at the highest point is (a) 3 : 2 (b) 2 : 1 (c) 4 : 1 (d) 4 : 3"
A ball is projected vertically upwards with a certain initial speed. Another ball of the same mass is projected at an angle of $60^{\circ}$ with the vertical with the same initial speed. At highest point of their journey, the ratio of their potential energies will be (a) $1: 1$ (b) $2: 1$ (c) $3: 2$ (d) $4: 1$
