The drawing shows a person looking at a building on top of which an antenna is mounted. the horizontal distance between the person’s eyes and the building is 95.2 m. in part a the person is looking at the base of the antenna, and his line of sight makes an angle of 30.4o with the horizontal. in part b the person is looking at the top of the antenna, and his line of sight makes an angle of 33.8o with the horizontal. how tall is the antenna?

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.
