Figure shows a simple model of spring-mass system. The mass is released from the rest with the springs un-stretched. It's downward acceleration is a=9.81 - 15.24y m/s2 where y is the position of the mass measured from the original position where it was released.
(a) Calculate:
i. The maximum y it falls.
ii. What is the maximum velocity it reached during the fall
(b) Derive a relationship for the position of the mass, y, as a function of time t.
Q. Write any three applications of laser in industry. Industrial applications (i) The laser beam is utilized to drill extremely fine holes in diamonds hard sheets etc.
