Gravitation Question 17
Question 17 - 01 February - Shift 2
For a body projected at an angle with the horizontal from the ground, choose the correct statement.
(1) Gravitational potential energy is maximum at the highest point.
(2) The horizontal component of velocity is zero at highest point.
(3) The vertical component of momentum is maximum at the highest point.
(4) The kinetic energy (K.E.) is zero at the highest point of projectile motion.
Show Answer
Answer: (1)
Solution:
Formula: Maximum height, Horizontal range
At highest point
$V_y=0$
$V_x=u_x=u \cos \theta$
$U_g=mgh$, it is maximum at $H _{\max }$
