An all female guitar septet is getting ready to go on stage. the lead guitarist, kira, who is always in tune, plucks her low e string and the other six members, sequentially, do the same. each member records the initial beat frequency fbeat, i between her low e string and kira's low e string. part a rank each member on the basis of the frequency of her low e string. rank from largest to smallest. to rank items as equivalent, overlap them.

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
