Consider a pure-rolling race where two objects a and b are simultaneously released from the top of an inclined plane and roll down to a finish line. for each group below, answer which object will win the race or it will be a tie (a or b or tie).
1.a: 100g solid cylinder with r = 10cm vs b: 200g solid cylinder with r = 10cm.
2. a: 100g solid cylinder with r = 10cm vs b: 100g solid cylinder with r = 20cm.
3. a: 100g solid cylinder with r = 10cm vs b: 100g hollow cylinder with r = 10cm.
4. a: 100g solid cylinder with r = 10cm vs b: 100g solid sphere with r = 10cm.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
