An object acted on by three forces moves with constant velocity. one force acting on the object is in the positive x direction and has a magnitude of 6.7 n; a second force has a magnitude of 4.5 n and points in the negative y direction. find the direction and magnitude of the third force acting on the object. ndegrees (counterclockwise from the +x axis)

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
