Two balls of different masses are thrown vertically upward with same initial velocity. Height attained by them are `h_1 and h_2` respectively. What is `h_1//h_2` ?

Explanation

To solve the problem, we need to determine the ratio of the heights attained by two balls of different masses when thrown vertically upward with the same initial velocity. Let's denote the heights attained by the two balls as \( h_1 \) and \( h_2 \).

### Step-by-Step Solution:

1. **Understanding the Motion**:
Both balls are thrown upward with the same initial velocity \( u \) and will rise until their velocity becomes zero at the maximum height.

2. **Using the Kinematic Equation**:
