Ahiker walked a hiking trail according to the chart below. what is a possible explanation of the hiker's movement? the hiker ended up in the same place that he started. the hiker got tired and walked the slowest from 1: 00-2: 00. the hiker stopped for lunch from 11: 00-12: 00 and that slowed him down. the hiker had an easy, level trail from 11: 00-12: 00 and was able to travel the fastest during that time period.

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.
