Why can you eliminate the solution of -0.2 in the context of this problem? Check all that apply.

The value −0.2 represents a time, and negative time would mean the ball hit the ground 0.2 time units before it was thrown. That is not possible in this situation, so the solution is eliminated. The ball’s height does not have to be positive at the instant it hits the ground; it is zero then, so choice A is not a reason to reject this time value.
