Problem 1-
In outer space, and constant net force of magnitude 136 N is exerted on a 32.3 kg probe initially at rest.

Part A- what accerleration does this force produce?

answer ... a=__________m/s^2

Part B- how far does the probe travel in 12.0 s?

answer ... t=__________m

Problem 2-
What is the mass of a book that weighs 3.20 N in the laboratory?

answer ... m=__________kg

In the same lab, what is the weight of a dog whose mass is 14.0 kg?

answer ... w=__________N
