I'm having a baby shower, and for one of the games I want to do matching between types of animals and the names of their babies (i.e. cow-calf, cat-kitten).
Whoever can tell me the most animal baby names will get the 10 points. Thanks!

An elevator weighing 20,000 N is supposed by a steel cable. What is the tension in the cable when the elevator is being accelrated upward at a rate of 3.0 m/s^2.

Would it be: (20,000)(3.0) + (20,000)(9.8) = 26,100N?

please help, I'm confused with this one, thanks!
