3. Two soccer players kick a ball simultaneously (at the same time) from opposite sides. Red #3 kicks with 50 N of force to the right while Blue #5 kicks with 63 N
of force to the left. What is the net force on the ball?
Can you explain the answer

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
