Question

A bullet is fired from a gun with speed 280 m s⁻¹ in a direction 30° below the horizontal. The maximum height attained by the bullet is: (g = 9.8 m s⁻², sin30°=0.5)

G1 Physics · Accepted Answer

Step 1: The vertical component magnitude is uᵧ=280 sin30°=140 m s⁻¹. Step 2: Maximum height relative to the projection level is H=uᵧ²/(2g). Step 3: H=140²/(19.6)=1000 m. Final answer: A.
