In the second set of problems below, you will be given the force applied to an
object and the acceleration of that object, and then will need to solve for mass,
using the equation m = F/a.
In other words, you will need to divide the force by
the acceleration to calculate the mass.
Show your work in the space provided.
sure to state the proper units in your answer, and state each answer to the nearest
tenth of a unit, to match the accuracy of the measurements.
