Anti-Aircraft Shell Vertical Ascent: Calculations and Velocities
Question: An anti-aircraft shell is fired vertically upwards with a muzzle velocity of 294 ms-1.Calculate Solution: (1) Anti-aircraft shell-Maximum height Condition for maximum height(H) is $${\sin^2\theta=1}$$ $${H=\frac{u^2}{2g}=\frac{294^2}{2(9.8)}}$$ $${H=(15)(294)=4410 \ m =4.41 \ Km}$$ (2) Time taken to reach maximum height Time taken to reach maximum height is $${t=\frac{u}{g}=\frac{294}{9.8}=30 \ s}$$ (3) Velocity at the end…
