A small spring is laying horizontal on a table and is compressed by 0.50 m. A small mass of 0.25 kg is placed in front of the compressed spring. a) When the spring is released it accelerates the box at a = 8.0m/s . What is the value of the spring constant, k for the spring? Ignore friction for part (a). b) When the small mass loses contact with the spring it moves over a part of the table where there exists a friction force between the small mass and the table. If the box comes to a stop after sliding 5.0 m, using your knowledge of work, find the coefficient of friction between the sliding mass and the table

Question
A small spring is laying horizontal on a table and is compressed by 0.50 m. A small mass of 0.25 kg is placed in front of the compressed spring.
a) When the spring is released it accelerates the box at a = 8.0m/s . What is the value of the spring constant, k for the spring? Ignore friction for part (a).
b) When the small mass loses contact with the spring it moves over a part of the table where there exists a friction force between the small mass and the table. If the box comes to a stop after sliding 5.0 m, using your knowledge of work, find the coefficient of friction between the sliding mass and the table.
