What is the velocity of mass A at point p What is the velocity of mass A at point Q what is the velocity of mass A just neform it strik spring 2 What is the max defection of spring 2

Solution

1) Using Consrvation of energy

     0.5 * k * x^2   = 0.5 * m * v^2

     100 * 1^2   = 10 * v^2

     v^2 = 10        or   v = 3.1623 m/s

2) Using Consrvation of energy

     m * g * h + 0.5 * m * v1^2   = 0.5 * m * v2^2

     10 * 9.8* 100 + 0.5 * 10 * 10 = 0.5 * 10 * v2^2

     v2 = 44.3847 m/s

3) Using Consrvation of energy

     0.5 * m * v2^2   = 0.5 * m * v3^2 + mu * m * g * d

     0.5 * 10 * 1970 = 0.5 * 10 * v3^2 + 0.5 * 10 * 9.8 * 100

     v3 = 31.464 m/s

4) Using Consrvation of energy

     0.5 * m * v3^2   = 0.5 * k * x^2

     10 * 990 = 100 * x^2

     x = 9.95 m
