003 (part 1 of 2) 10.0 points Assume: Down the plane is the positive direc- tion and up the plane is the negative direction. A block of mass 260 kg slides on a friction- less plane inclined at 39° with the horizontal under the influence of a restraining force of 1393 N acting parallel to the incline and up the incline. The acceleration of gravity is 9.8 m/s².
F 260 kg 39° What is the magnitude of the acceleration a of the block? Answer in units of m/s². 004 (part 2 of 2) 10.0 points The resulting motion is 1. down the plane, since the acceleration is positive. 2. undetermined. 3. up the plane, since the acceleration is negative.
