Q1. A 12 kg box slides 4.0 {rm m} down the frictionless ramp, and then collides with a spring whose spring constant is 240 N/m.
Q2. Jeff of the Jungle swings on a 7.6 {rm m} vine that initially makes an angle of 47{rm ^circ} with the vertical.
If Jeff starts at rest and has a mass of 73 {rm kg}, what is the tension in the vine at the lowest point of swing?
