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.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
