6. RADIOACTIVE DECAY A radioactive element decays exponentially. The decay model is given by the formula
A= Ao e^-0.04463t . A is the amount present after 1 days and Ao is the amount present initially. Assume you are starting
with 50g. How much of the element remains after 10 days? 30 days?

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.

Which of the following are appropriate acceleration units?
