Question 121: Gravitation

Question

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

Accepted Answer

At highest point height is maximum and vertical component of velocity is zero.
So momentum is zero.
At highest point horizontal component of velocity will not be zero but vertical component of velocity is equal to zero and because of this K.E. will not be equal to zero.
Gravitational potential energy is maximum at highest point and equal to $\mathrm{mgH}=$$$mg\left( {{{{u^2}{{\sin }^2}	heta } \over {2g}}} ight)$$

Answer

Gravitational potential energy is maximum at the highest point.

Answer

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

Answer

The horizontal component of velocity is zero at the highest point.

Answer

The Kinetic Energy (K.E.) is zero at the highest point of projectile motion.
