010 (part 1 of 2) 10.0 points A 28.5 kg mass attached to a spring scale rests on a smooth, horizontal surface. The spring scale, attached to the front end of a boxcar, reads T = 27.1 N when the car is in motion. If the spring scale reads zero when the car is at rest, determine the acceleration of the car, when it is in motion as indicated above. Answer in units of m/s². 011 (part 2 of 2) 10.0 points What would be the reading on the scale if the boxcar were moving at a constant velocity? 1. greater than T 2. There is not enough information given to tell which is correct. 3.0 N 4. T 5. less than T, but greater than 0 N
