A 14.5 kg wheelbarrow starts at the bottom of an incline traveling at a speed of 19.4 m/s. The wheelbarrow then goes up a grassy incline with friction a distance of 6.7m and decreases speed to 9.5 m/s. the height of the incline is 0.8m. what is the magnitude of the frictional force exerted on the wheelbarrow? please when you answer don’t send the link cause the link not opening college level

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.
