Question

Can someone please explain how to do #5?? Please and Thank you!

Use the following information for questions 2 5: A 5.0kg mass and an 8.0kg mass collide. Prior to the collision the velocity of the 5.0kg mass was esi-4.0% E and that of the 8.0kg mass was Uni- 1.0 + 3.0쯤j. After the collision the velocity of the 5.0kg mass is v5f- 3.0 2. What is the total momentum immediately after the collision? (a) 8.0%8mî+ 9.0 kg,mj (b) 8.0*9mi+24.0*9mj (c) 15.0*?mj (d) 20.0% (e) 28.0讐计24.0kg,mj 3. What is the speed of the 8.0kg mass immediately after the collision? In other words, what is lvsfl? (a) 3.0m (b) 3.2m (c) 3.57m2 (e) 4.0m 4. What angle relative to the x-axis (to î) does the final momentum of the 8.0kg mass make? * 18 (b) 37° 0 (d) 49° (e) 71° 5. Assuming that the collision took 0.5s to occur, what is the magni tude of the average force on the 5.0kg mass? In other words, what is avg,5 (a) 10N (b) 13N (c) 25N (d) 50N (e) 74N
