ok got it. each half will have a spring constant of 2k. thanks for your help!

Homework Statement A simple pendulum is made from a 0.653 m-long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed...

thanks so much!

so m1=167-m2 (167-m2)(.897) + m2(1.09)=0 distribute 149.799-.897m2 + 1.09m2=0 combine like terms 149.799+.193m2=0 .193m2=-149.799 m2=-776.16 (which can't be right, because one, it's negative, and two, the masses have to add up to 167, and 776.16 is obviously larger) did i make a math...

Homework Statement Two friends, Al and Jo, have a combined mass of 167kg. At an ice skating rink they stand close together on skates, at rest and facing each other, with a compressed spring between them. The spring is kept from pushing them apart, because they are holding each other. When they...
