📘 **Physics XI – Model Paper 2026 | Work & Power**

A man of **mass 70 kg** climbs a **height of 3 m** in **2 seconds**.
Find **Work Done** and **Power**.

Work = mgh
W = 70 × 9.8 × 3 ≈ **2058 J**

Power = W / t
P = 2058 / 2 ≈ **1029 W**

🎯 **At What Angle Does Range = Maximum Height? | Projectile Motion**

Do you know the launch angle at which the **range of a projectile becomes equal to its maximum height?** 🤔

Using projectile motion formulas and solving **R = H**, we get:

**tanθ = 4**

So the required angle is approximately **76°** 🚀
