Q. A ball is projected with velocity $V_{o}$ at an angle of elevation $30{^\circ}$ . Mark the correct statement
A) Kinetic energy will be zero at the highest point of the trajectory
B) Vertical component of momentum will be conserved
C) Horizontal component of momentum will be conserved
D) Gravitational potential energy will be minimum at the highest point of the trajectory
Explanation
(c) Since horizontal component of velocity is constant, hence momentum is constant
