1. A 3 kg block collides with a massless spring of spring constant 90 N/m attached to a wall. The speed of the block was observed to be 1.5 m/s at the moment of collision. The acceleration of gravity is 9.8 m/s^2. How far does the spring compress if the surface on which the mass moves is frictionless?

2. The maximum distance to which the spring was compressed was observed to be 16.4317 cm. What is the kinetic coefficient of friction between the block and the floor?

3. Given: The coefficient of static friction between the floor and the block is 0.670681. Does the block remain at rest or does it
bounce back off the spring once the spring is fully compressed?
1.stays at rest
2.cannot be determined
3.bounces back
