We are given the following conditions:

Since we are told it slows down at a constant rate, we know we are dealing with uniformed accelerated motion, or UAM for short.
So we look at our kinematics equation that contains the given variables.

This contains our target variable and our initial conditions. Plug and chug, we get:

Thus the answer is:
a = -7m/s^2
Hope this helps!
Crude oil, coal, natural gas. All of these pollute the Earth when there are consumed and have a certain amount available. Renewable resources are infinite in value.
For number one the answer is Iodine because it is in the same group as fluorine. For number two the answer is Germanium for the same reason. For number three the answer is Aluminum for the same reason.
