For a body projected at an angle with the horizontal from the ground, choose the correct statement

For a body projected at an angle with the horizontal, choose the correct statement.

Analysis of each option:

Option (1): "Gravitational PE is maximum at the highest point."

PE = mgh. At the highest point, h is maximum, so PE is maximum. TRUE.

Option (2): "Horizontal component of velocity is zero at highest point."

The horizontal velocity remains constant (no horizontal force). Only the vertical component becomes zero at the top. FALSE.

Option (3): "Vertical component of momentum is maximum at highest point."

The vertical component of momentum is zero at the highest point (vertical velocity = 0). FALSE.

Option (4): "KE is zero at the highest point."

At the highest point, the body still has horizontal velocity, so KE is not zero. FALSE.

The correct answer is Option (1).
