Question

The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is:

G1 Physics · Accepted Answer

Step 1: At maximum height, only the horizontal component remains, so vₜₒₚ=u cosθ. Step 2: Given vₜₒₚ=u/2, cosθ=1/2. Step 3: Therefore θ=60°. Final answer: A.
