Hi, i need help for two physics problems.

Problem n.1

Collision and Conservation of Mechanical Energy (Spring+ block (+putty)) A 0.440-kg block is attached to a horizontal spring that is at its equilibrium length (Natual length), and whose force (spring) constant is 22.0 N/m . The block rests on a frictionless surface. A 5.1 0x10'2-kg wad of putty is thrown horizontally at the block, hitting it with a speed of 2.30 m/ s and sticking. v PartA Process 1: The collision between the block and the putty. What is the common final speed of the Block + Putty immediately after the collision? Keep 3 digits after the decimal point, in m/s. Immediately after the collision, final speed = : m/s Submi Previous Answers Request Answer Incorrect; Try Again; 4 attempts remaining .0
