A mass of 0.5 ~kg moving with a speed of 1.5 ~m / s on a horizontal smooth surface, collides with a nearly weightless spring of force constant k=50 ~N / m . The maximum compression of the spring would be:
Options
- A0.15 ~m
- B0.12 ~m
- C1.5 ~m
- D0.5 ~m
Correct answer
A. 0.15 ~m
Step-by-step solution
According to the question aligned 1 2 m v^2 & = 1 2 k x^2 x & =v m k =1.5 0.5 50 & =0.15 ~m aligned
