A motorboat travels at 8.5 m/s relative to the water. It heads due east across a river 110 meter wide that flows due south. If the water flows at a rate of 3.8 m/s what is the boats resultant velocity with respect to the shore

How much time does it take the boat t reach the opposite shore?

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.
