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

Gravitational potential energy is maximum at the highest point.

The horizontal component of velocity is zero at highest point.

The vertical component of momentum is maximum at the highest point.

The kinetic energy (K.E.) is zero at the highest point of projectile motion.

An object moves with speed v 1 , v 2 and v 3 along a line segment A B , B C and C D respectively as shown in figure. Where A B = B C and A D = 3 A B , then average speed of the object will be :

3 v 1 v 2 v 3 v 1 v 2 + v 2 v 3 + v 3 v 1

v 1 v 2 v 3 3 v 1 v 2 + v 2 v 3 + v 3 v 1
