object of mass m = 4.75 kg, attached to a spring scale, rests on a frictionless, horizontal surface as in t figure below. The spring scale, attached to the front end of a boxcar, reads zero when the car is at rest. spaccom Ⓡ (a) Determine the acceleration of the car if the spring scale has a constant reading of 17.5 N when the car is in motion. m/s² to the right (b) What constant reading will the spring scale show if the car moves with constant velocity? N (c) Describe the forces on the object as observed y someone in the car. This answer has not been graded yet. (d) Describe the forces on the object as observed by someone at rest outside the car. This answer has not been graded yet
