Question

The small 0.1-kg slider enters the “loop-the-loop” with a speed υa = 12 m/s as it passes point a, and it has a speed υb = 8 m/s as it exits at point b. Determine the work done by friction between points a and b. The track lies in a vertical plane. Assume that contact is maintained throughout. 

1. The small 0.1-kg slider enters the "loop-the-loop" with a speed Va = (A+4) m/s as it passes point a, and it has a speed Db = A m/s as it exits at point b. Determine the work done by friction between points a and b. The track lies in a vertical plane. Assume that contact is maintained throughout. A is the last digit of your student number replacing any 0 with 10. For example, if your student number is 400027581 then A = 1, if your student number is 400027580 then A = 10, etc. 2.45 m 0.8 m a
