Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations. Motion - ...

For this problem, the "Given" information is in terms of the Cartesian kinematical description. The "Find" asks for parameters that are part of the path kinematical description. Recall that the sign ...
