Most Important Selected Qs for JEE AdvancedPhysicsOscillations
Paragraph: Figure shows block A of mass 0.2 kg sliding to the right over a frictionless elevated surface at a speed of 10 ~m / s . The block undergoes a collision with stationary block B , which is connected to a non-deformed spring of spring constant 1000 Nm ⁻¹ . The coefficient of restitution between the blocks is 0.5. After the collision, block B oscillates in SHM with a period of 0.2 s, and block A slides off the
Options
- A2 m
- B2.5 m
- C4 m
- D6.25 m
Correct answer
B. 2.5 m
Step-by-step solution
Time of flight = 2 ~h ~g =1 ~s ~d =(2.5 ~m / s ) 1 ~s =2.5 ~m
