A20-kg crate is sitting on a frictionless ice rink. a child standing at the side of the ice rink uses a slingshot to launch a 1.5-kg beanbag at the crate. assume that the beanbag strikes the crate horizontally in the +x direction with a speed of 10 m/s. the beanbag bounces straight back in the -x direction with a speed of 6 m/s. using conservation of momentum, calculate the speed of the crate after the beanbag hits it.

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?
