A 2.10-kg frictionless block is attached to an ideal spring with force constant 355 N/mN/m. Initially the spring is neither stretched nor compressed, but the block is moving in the negative direction at 15.0 m/s

A)Find the maximum acceleration of the block.

Express your answer in meters per second squared.

B)Find the maximum force the spring exerts on the block.

Express your answer in newtons.
