To solve the problem of determining the time elapsed before the horizontal and vertical velocities of a body projected horizontally from a cliff become equal, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Information:** - Horizontal velocity (u_x) = 9.8 m/s - Initial vertical velocity (u_y) = 0 m/s (since the body is projected horizontally) - Acceleration due to gravity (g) = 9.8 m/s² (acting downwards) ...
