Question
A 22.7 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 = 21.9 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.
