Question

A particle is projected vertically upward and returns to its point of projection after time T. Which statements are correct?

G1 Physics · Accepted Answer

For a complete return to the same level, T = 2u/g ⇒ u=gT/2. Maximum height: H = u²/(2g) = gT²/8. Total distance for the complete flight is 2H: 2H = gT²/4. Average speed: (2H)/T = gT/4. Net displacement is zero, so average velocity is zero. All statements are correct.
