A spring-loaded toy gun projects a 6.1 g nerf pellet horizontally. The spring constant is 8.5 N/m, the barrel of the gun is 13 cm long, and a constant frictional force of 0.039 N exists between the barrel and the nerf pellet. If the spring is compressed 6.6 cm for this launch, determine the speed (in m/s) of the pellet as it leaves the barrel. (Assume the pellet is in contact with the barrel for the full length of the barrel.)

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?
