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

Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: Two identical balls $A$ and $B$ thrown with same velocity ' $u$ ' at two different angles with horizontal attained the same range $R$ . If A and $B$ reached the maximum height $h_{1}$ and $h_{2}$ respectively, then $R = 4 \sqrt{h_{1} h_{2}}$

Reason R: Product of said heights, $h_{1} h_{2} = (\frac{u^{2} \sin^{2} θ}{2 g}) \cdot (\frac{u^{2} \cos^{2} θ}{2 g})$ .
