1. The problem statement, all variables and given/known data Two football players collide at an angle of 90 degree and stick together after the collision. Before the collision, player A (m= 125kg) had a speed of 4m/s and player B (m=100kg) had a speed of 5m/s. 1)Calculate the total momentum of the players and the final velocity they had after the collision. 2)Calculate the angle a between the direction player A had before and after the collision. (hint: use tan a=Pa/Pb ). 2. Relevant equations I believe: a^2 + b^2 = c^2 p=m/v v=v/m 3. The attempt at a solution To find total momentum, I first calculated momentum for each player: Player A = 125kg divided by 4m/s = 31.25 kg. m/s Player B = 100kg divided by 5m/s = 20 kg. m/s Pt^2 = (20)^2 + (31.25)^2 = 400 + 977 = +/- 37. To find vf = p/m = 37/125+100 (total mass) = 0.16m/s. What do you guys think?
