- A spring with relaxed length 0.30 m and spring constant 1.8 N/m rests horizontally on a frictionless table and is anchored frmly to a wall on one side. You press a 400 g block into the other side until the spring length is 0.16 m and then let go. a.) What will the momentum of the block be when it departs from the spring? (Assume contact ceases when the spring is relaxed.) b.) If the table were no longer frictionless and the block-table interface had a kinetic coeffcient of friction of 0.1 what then would the momentum of the block be when it departs from the spring?If instead the collision is completely inelastic, calculate the max angle in degrees reached after collisionSolve using the linear impulse and momentum equation.
