1. If a 0.4 kg object hanging from a spring stretches it by 0.90 m, then by how much will the spring be stretched (in m) if a 0.8 kg object is suspended from It?
2. Suppose an airline allows a maximum of 29 kg for each suitcase a passenger brings along.
(a) What is the weight in newtons of a 29 kg suitcase?
(b) What is the weight in pounds?
(c) The mass of a subway car and passengers is 30,500 kg. If its acceleration as it leaves a station is 0.5 m/s?, what is the net force (in N) acting on it?
