An object moves along the x-axis. It is moving in the negative x-direction with increasing speed. The xcomponents of its velocity and acceleration are: A) both positive B) velocity negative, acceleration positive C) both negative D) velocity positive, acceleration negative correct answers C) both negative The position of an object in one dimensional motion as a function of time t is given by x(t) = q - bt2 + ct3 where q, b, and c are positive constants. At t = 0, the object's position, veloc...
