dear students, let’s analyze the oblique collision in two dimensional plane . here we are given, 2 balls of masses, m 1 and m 2, moving with initial speeds u 1 and u 2 in different directions, they collide at a point , and, bounce in different directions, with speeds v 1 and v 2 […]

in this example, it is given that a ball is released , from a height h above a floor with coefficient of restitution e , between floor and ball. we are required to find the number of bounces ball will take before coming to rest . and we are also required to find the total […]

in this example we are given two identical bars, which are connected by an ideal spring of natural length l knot, it is also given that its force constant is k , as shown , and a constant horizontal force f starts acting on one of the bars as shown, we are required to find […]

in this example it is given that a neutron moving at a speed v undergoes a head on elastic collision with a nucleus of mass number-a at rest . we are required to find the ratio of ki-netic energies of neutron after and before collision. now, let’s analyze this situation, we are given that a […]

Alright guys. Let’s talk about books. The most common questions all these aspirants ask is – What books to follow, how many books to follow? And how to go about preparing form these books; in the sense that are the text books sufficient? Or are the books (coaching materials) given by coaching institutes sufficient? Or […]

this example says a ball is dropped on a floor from a height h, if coefficient of restitution is e we are required to find the height to which ball will rise after rebound . we just analyze the situation in this problem we can see , on a floor a ball is dropped from […]

in this example again we are given a flat car of mass capital m with a child of mass small m, is moving at speed v-one , here the flat car is moving with speed v-one , and given that the child jumps in the direction of motion of car with a velocity u , […]
