The velocity and acceleration of an object at a certain instant are v =(3.0m/s)j a= (0.5 m/s' )1 (0.2 m/s' )] At this instant, the object is A. speeding up and following a curved path. B. speeding up and moving in a straight line. V C. slowing down and following a curved path. D. slowing down and moving in a straight line. E. none of these. The velocity and acceleration of an object at a certain instant are V = (2.0 m/s2 ) i + (3.0 m/s) j a = (0.5 m/s2 )i - (0.2 m/s2 ) j At this instant, the object is A. speeding up and following a curved path. B. speeding up and moving in a straight line. C. slowing down and following a curved path. D. slowing down and moving in a straight line. E. none of these
