A block of 4 kg mass starts at rest and slides a distance d down a frictionless incline (angle 30°) where it runs into a spring of negligible mass. The block slides an additional 25 cm before it is brought to rest momentarily by compressing the spring. The force constant of spring is 400 N/m. the value of d is then
(take g = 10 ms–2)
(take g = 10 ms–2)
- 25 cm
- 37.5 cm
- 62.5 cm
- none of the above
Answer
(B) 37.5 cm
