Chapter 2, Problem 6Q
At t = 0, a particle moving along an x axis is at position x0 = −20 m. The signs of the particle’s initial velocity v0 (at time t0) and constant acceleration a are, respectively, for four situations: (1) +, +; (2) +, −; (3) −, +; (4) −, −. In which situations will the particle (a) stop momentarily, (b) pass through the origin, and (c) never pass through the origin?

A particle starts from the origin at t 0 with a velocity of 8.0 m/s and moves in the xy plane with constant acceleration (4.0 2.0 ) m/s2.When the particle’s x coordinate is 29 m, what are its (a) y coordinate and (b) speed?
Question 3: The relation of the magnitude of the acceleration and the speed
of a particle is given by
a = -av?
where a, a, and v are the magnitude of the acceleration, a positive number,
and the speed, respectively. The particle starts the motion at the origin,
= 0) = 0, with initial speed vo. What is constant a (in the appropriate
unit) if the speed of the particle becomes vo/2 at x = 2 meters.
