Three masses are connected via light strings and an ideal pulley, as shown below. Mass m2 is twice as massive as m1; m3 is three times as massive as m1. Everything is initially at rest, but then m3 is released, and it falls 1. 30 m to the floor. If the speed of m3 just before it hits the floor is 3 m/s, what is the coefficient of kinetic friction between the table and the blocks? (hint: use an energy analysis. ).

Of four agents alpha, beta, gamma anddelta, three have to be sent together on amission. if alpha and beta cannot gotogether, beta and gamma cannot go togetherand gamma and delta cannot go together,then which of the following holds? 1. any three agents can be sent.2. alpha, delta and any one out of beta andv gamma can be sent.3. beta, gamma and any one out of alphaand delta can be sent.4. the mission is impossible.
