The student has access to the following measurement equipment: a spring scale, a meterstick, and a stopwatch. the student uses the spring scale to pull the cart starting from rest along a horizontal surface such that the reading on the spring scale is always constant. all frictional forces are negligible. in addition to the spring-scale reading, which two of the following quantities could the student measure with the available equipment and then use to determine the inertial mass of the cart? select two answers.

a) the total distance traveled by the cart after it has been in motion
b) the average speed of the cart while in motion
c)the acceleration of the cart while in motion
d)the time during which the cart is in motion
