(a).the speed of the combined mass immediately after the collision with respect to an observer on the ground. The wedge makes an elastic collision with the fixed sphere and returns along the same path,any rotation* Neglect all friction and suppose that the wedge remains in contact with the sphere for a very short time Δt during which the sphere exerts a constant force F‾ on the wedge. Then the maximum extension in the spring is . a. Preparing for entrance exams? They can get the experience of giving a real exam while solving a past year JEE question paper to become confident for the upcoming JEE exam. A small object of mass m moving horizontally along a line passing through the centre of mass (COM), of the block B and perpendicular to its face with a speed v collides elastically with the block B at a height d above the table. (b).the length L of the string such that the tension in the string becomes zero when the string becomes horizontal during the subsequent motion of the combined mass. (c).After how many impacts, does the laminar sheet come to rest ? The balls are colliding elastically with velocity v. What is v? Ask Question . At the highest point in its path it explodes into two pieces of equal mass. Practicing JEE Advanced Previous Year Papers Questions of Physics will help the JEE aspirants in realizing the question pattern as well as help in analyzing weak & strong areas. All About JEE. It deals with the study of Motion. There is no friction between any surfaces of contact. At this position the string snaps. The books have chapters aligned in appropriate order (as per the NCERT books).

AB, BC and CD are straight line segments. 10.Two blocks A and B, each of mass m, are connected by a massless spring of natural length L and spring constant K. The blocks are initially resting on a smooth horizontal floor with the spring at its natural length, as shown in figure. (equate all parts:). JEE Main Physics Chapter-wise Solved Questions (Sep 2020) – PDF Download. At the highest point of its trajectory, it collides head-on with a bob of mass 3M suspended by a massless string of length (10/3)metre and gets embedded in the bob, After the collision, the string moves through an angle of 120°. Their tangential velocities are v and 2v, respectively, as shown in the figure. A third identical block C, also of mass m, moves on the floor with a speed v along the line joining A and B, and collides elastically with A. IIT JEE Blog. 14.Statement -1 In an elastic collision between two bodies, the relative speed of the bodies after collision is equal to the relative speed before the collision, Statement -2 In an elastic collision, the linear momentum of the system is conserved * [2009-3 marks], (a).Statement -1 is True, Statement -2 is True; Statement-2 is a correct explanation for Statement-1, (b).Statement -1 is True, Statement -2 is True; Statement-2 is not a correct explanation for Statement-1, (c).Statement -1 is True, Statement -2 is False, (d).Statement -1 is False, Statement -2 is True, 15.A body of mass m moving with a velocity v in the x-direction collides with another body of mass M moving in the y-direction with a velocity V. They collapse during collision. Does this violate the conservation of momentum principle? IIT-JEE … 27.An object’of mass 5kg is projected with a velocity of 20m/s at an angle of 60° to the horizontal. IIT-JEE Mechanics Questions!
