At a race car driving event, a staff member notices that the skid marks left by the race car are 10.99 m long as it comes to a stop. The very experienced staff member knows that the
deceleration of a car when skidding is -42.61 m/s2. What can the staff member estimate for
the original speed of the race car if it came to a stop during the skid?

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.
