An artist creates a solid sculpture made from 7.60 kg of aluminum. She wishes to create an identical sculpture, using the same mold used to make the original, out of solid silver. What is the mass (in kg) of the silver sculpture? (The density of aluminum is 2.70 ✕ 103 kg/m3, and that of silver is 10.50 ✕ 103 kg/m3.)

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.
