The speed of an object is the magnitude of its relative velocity vector . A baseball player throws a baseball at an angle of 61° with the horizontal. If the initial speed of the ball is 93 mph, find the horizontal and vertical components of the initial velocity vector of the baseball. (Round to two decimal places.)
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
