JEE Advanced Physics 2022 Paper 1: #16 Relative Velocity (Vectors) Part 2

To donate:

List I describes four systems, each with two particles A and B in relative motion as shown. List II gives possible magnitudes of their relative velocities (in m/sec) at time pi/3 sec.
Part II: Projectiles A and B are fired in the same vertical plane at t=0 and t=0.1sec respectively with the same speed v=[5(pi)]/SQRT(2)m/sec and at 45 degrees from the horizontal plane. The initial separation between A and B is large enough so that they do not collide (g=10m/sec^2).
(A) 1 implies R, 2 implies T, 3 implies P, 4 implies S
(B) 1 implies S, 2 implies P, 3 implies Q, 4 implies R
(C) 1 implies R, 2 implies T, 3 implies P, 4 implies R
(D) 1 implies T, 2 implies P, 3 implies R, 4 implies S

Sir, why should we consider 0.1 sec . In question we were asked to find relative velocity at pi/3 right. It means we should find final velocity vectors of particle A and B at pi/3.If question mentions same height in Pi/3 sec then we should subtract 0.1sec right.

Sir I have a question. At 3:22, the Vb = (-10)(π/3 - 0.1). Particle B is taking off 0.1 seconds later. At π/3 seconds particle A will cover the distance that it should but particle B won't cover the distance that it should because it is 0.1 seconds late. Why shouldn't I add 0.1 seconds with π/3 seconds in order to really complete π/3 seconds ?

Sir I have a request also . Sir please make video solutions of Question no. 4, 5, 6 from Paper 1 and Q 4 from Paper 2 of Mathematics of JEE Advanced 2022

Sir, what do you consider? In a populous country like India, these kind of questions aren't hard for high schoolers to solve, and they are just for rejecting the candidates.

[HrishikeshVinod]

Thank you so much Professor for this. Also Sir, please kindly consider my suggestion: Could you make a video on how to solve SHM problems using Taylor Series? [This is a very useful trick some of the Olympiad aspirant use to solve SHM problems quickly in JEE exams]. I was very curious to learn that concept but all the tutorials available are not in English. This is a humble request as the way you explain in on another scale:).
