QAIPMT-2004-Ph-2647: NEET 2004 Physics - Class 11 AIPMT-2004-Ph-2647 Solution: A mass of 0.5 kg moving with a speed of 1.5 m/s on horizontal…
A mass of 0.5 kg moving with a speed of 1.5 m/s on horizontal smooth surface, collides with a nearly weightless spring of force constant k = 50 N/m. The maximum compression of the spring would be
Multiple Choice Options
- A 0.15 m
- B 0.12 m
- C 1.5 m
- D 0.5 m
Step-by-Step Verified Solution
It is observed that if mass colloids with spring
in such case, spring will be compressed, so kinetic
energy of mass will be equal to that of springs
potential energy.
Further, if y is the compression, then
1 2 m v 2 = 1 2 k y 2
_ 1 2 ( 0.5 ) ( 1.5 ) = 1 2 ( 50 ) y 2
_ y = 0.15 m
