2.26 kg book is dropped from 1.5 m. What is the acceleration?
What is the weight in newtons?

A clue: the height it's dropped from doesn't matter.

What do you think the answers are?

I have no idea...
What formulas would solve the two questions?

For the first one you don't need a formula. For the second one, F=ma.

Is the acceleration for the first one 9.81? Since its at free fall?

Yes. Acceleration near earth is indeed 9.81 m/s. Newtons are the SI equivalent of pounds to the American system. We are just so hard headed and refuse to adopt another system.
