Vector quantities are those quantities that can need both magnitude and direction for their complete description. These quantities follow vector algebra.
Option a is correct because velocity, acceleration and force, all are vector quantities.

4. At which point or points is the net force on the mass equal to zero? Explain your reasoning. 5. At which point or points are the acceleration, velocity, and displacement all positive? Explain your reasoning. A mass is oscillating up and down at the end of a spring similar to Activity 2. A graph of displacement as a function of time is shown where up is the positive direction.

A car with mass ? travels in the +?-direction on a straight and level road with a constant acceleration ?. The car starts moving at time = 0. Find the followings quantities of the car in terms of ?, ?, ?. (1) average velocity between time = 0 and ? (2) instantaneous velocity at time = ? (3) ?-position at time = ? (4) Total work between time = 0 and ? (5) kinetic energy at time = ? (6)...
The only force F~ acting on a body of mass m (in kg) changes in time t according to F~ (t) = (F0 sin(ωt), F0 cos(ωt)) where F0 is a constant with units of N and the greek letter ω is a constant with units of radians/s. (Technically a radian is dimensionless, but I’ve explicitly stated it to clarify the problem.) Assume all arbitrary constants that appear due to indefinite integration are zero. (a) What is the acceleration vector of...
Rod OB, of length 1, rotates about with a constant absolute angular velocity of . At the same time, rod BA, of length 12, rotates about B with a constant angular velocity of or relative to rod OB. At the instant shown, determine (note: all answers must be expressed by the unit vectors i and j): (a) The absolute angular velocity of the rod BA (5 pts). (b) The position vector from point B to point A expressed by i...
