One of the difficulties in studying mechanics is that many common words are used with highly specific technical meanings, among them velocity, acceleration, position, speed, and displacement. the series of questions in this problem is designed to getyou to try to think of these quantities like a physicist. answer the questions in this problem using words from the following list: a. position b. direction c. displacement d. coordinates e. velocity f. acceleration g. distance h. magnitude i. vector j. scalar k. components
part a velocity differs from speed in that velocity indicates a particle's of motion. enter the letter from the list given in the problem introduction that best completes the sentence.
part b unlike speed, velocity is a quantity. enter the letter from the list given in the problem introduction that best completes the sentence.
part c a vector has, by definition, both and direction. enter the letter from the list given in the problem introduction that best completes the sentence.
part d once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as the letter from the list given in the problem introduction that best completes the sentence. d part e speed differs from velocity in the same way that differs from displacement.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
