A 0.550 kilogram block slides on a frictionless horizontal surface with a speed of 1.10 m/s. The block encounters an unscratched spring and compresses it 20 centimeter before coming to rest.
Part A. Obtain what is the force constant of this spring?
(N/m)
Part B. Determine for what length of time is the block in contact with the spring before it comes to rest?
(s)
Part C. If the force constant of the spring is increased, does the time required to stop the block increase, decrease, or stay the same?
