Q1. Two skaters with masses of 6 kg and 45kg, respectively stand 8.00 m apart each holding one end of a rope. If they pull themselves along the rope until they meet how far does each skater travel? B) If only the 45kg skater pulls along the rope until she meets her friend (who just holds onto the rope) how far does each skater travel?

Q2. A train is travelling up a 4.40 incline at a speed of 3.30 when the last car breaks free and begins to coast without friction. How long does it take for the car to come to rest? How far does the car travel?
