Answer:
Total distance covered horizontally S= 21.44 m
Explanation:
Given: Height h=2.2 m, Speed Vx=32 m/s
Required: Total distance covered horizontally S=?
Sol. we have
Distance = Speed (horizontal component)× Time
so we fist calculate time to the ground. so using data
Initial Velocity Vyi = 0 m/s (Zero Vertical component as launched horizontally).
g = 9.81 m/s²
using equation h = Vyi t + 1/2 (at²)
⇒ 2.2 m = 0 m/s ×t + 4.905 m/s² × t²
t² = 2.2 m / 4.905 m/s² = 0.4485219164118247 s²
t = 0.67 s
Total distance covered horizontally S= 32 m/s × 0.67 s = 21.44 m
