Question

A particle is projected at an angle of 30° with the horizontal with a momentum P. At the highest point its momentum is (A) (√3/4) P  (B) (2/√3) P  (C) P (D) (1/2)P

Tardigrade Admin · Accepted Answer

P = mu P1 = m ( u cos θ) = mu (√3/2) = (P √3/2)

Q. A particle is projected at an angle of $3 0^{\circ}$ with the horizontal with a momentum P. At the highest point its momentum is

$\frac{3}{4} P$

$\frac{2}{3} P$

$P$

$\frac{1}{2} P$

$P = m u$
$P^{1} = m (u cos θ)$
$= m u \frac{3}{2} = \frac{P 3}{2}$
