Problem: A biologist is studying the growth of rats in an orbiting space station. To determine a rat's mass, she puts it in a 330g cage, attaches a spring scale, and pulls so that the scale reads 0.44N.

Part A: If the resulting acceleration of the rat and cage is 0.45m/s², what is the rat's mass?

This is a physic problem, reply as soon as possible. Thanks.
