Two friends, Barbara and Neil, are out rollerblading. With respect to the ground, Barbara is skating due south at a speed of 3.3 m/s. Neil is in front of her. With respect to the ground, Neil is skating due west at a speed of 3.0 m/s. Find Neil's velocity (a) magnitude and (b) direction relative to due west, as seen by Barbara.

Which of the following correctly describes the early view of catastrophism?

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?

For waves in the ocean, the medium of the waves is a. air b. water c. energy d. a passing boat
