D Question 31 4 pts For a certain interval of time, an object is acted on by a constant non-zero force. Which of the following statements is true for this interval of time? The object's velocity can only increase. O The object is at rest. The object is moving with constant velocity. The object's velocity changes. D Question 32 4 pts The velocity versus time graph for an object is shown in the diagram below. What is the direction of the acceleration of the object for C to D time intervals? v (t) B t (s)D Question 32 4 pts The velocity versus time graph for an object is shown in the diagram below. What is the direction of the acceleration of the object for C to D time intervals? v ( t ) B t (s) O negative direction the acceleration is zero O acceleration has no direction positive direction D Question 33 6 ptsQuestion 30 6 pts Two forces P- and Q- act on an object of mass 17.0 kg with Q- being the larger of the two forces. When both forces are directed to the left, the magnitude of the acceleration of the object is 1.20 m/s2. However, when the force P. is directed to the left and the force Q- is directed to the right, the object has an acceleration of 0.600 m/s2 to the right. Find the magnitudes of the two forces P- and Q- in newtons. O P = 2.45 N; Q = 6.65 N O P =15.3 N; Q = 5.1 N O P = 6.65 N; Q = 2.45 N O P =5.1 N; Q = 15.3 N D Question 31 4 pts For a certain interval of time, an object is acted on by a constant non-zero force.
