Question

Info Pendulum 1 is released from an elevated position at t-0. It swings downward and collides inelastically with pendulum 2 which is at rest before the collision. Both pendula then swing upward together, reaching the top point of the swing at t t3 Let's define ty to be the instant right before the collision, and t2 to be the instant right after the collision t-0 Assuming that the collision happens nearly instantaneously. t2 1. for the system that includes both pendula, the momentum is conserved: At any time between 0 and t3 Between 0 and t1 only Between t and t2 only Between 0 and t and between t2 and t3 but NOT betweern t and t2 Between t2 and t3 only Submit Answer Tries 0/4

Answer 1

Solution : hce Vely As t ~t, so change in time at is very small and hence Impulse (J) = fat is very small. So Impulse 0. So momentum is conserved o At any time between 0 and t₃
