Rotational Motion question

2023 · 29 Jan · Shift 2 · Q62

JEE MainPhysicsRotational MotionNumerical+4 / −1
A particle of mass 100 g is projected at time t = 0 with a speed 20 ms −1^{-1}−1 at an angle 45 ∘^\circ∘ to the horizontal as given in the figure. The magnitude of the angular momentum of the particle about the starting point at time t = 2s is found to be K kg m2/s\mathrm{\sqrt K~kg~m^2/s}K​ kg m2/s. The value of K is ‾\underline{\hspace{2cm}}​. (Take g = 10 ms −2^{-2}−2) JEE Main 2023 (Online) 29th January Evening Shift Physics - Rotational Motion Question 66 English
