Answer:
Yes.
Explanation:
This is because "negative velocity" just means it is in the negative in relation to the point of 0. Negative velocity doesn't equal a decrease in velocity. For example lets say you were parked next to a cone (this cone represents zero) if you accelerate forwards then that would be positive acceleration. If you were to accelerate backwards, this would be in the negative direction, aka negative velocity.
SUMMARY:
A negative velocity means that the object which has the negative velocity is moving in the opposite direction of an object moving at a positive velocity. This is a question of frame of reference. The possibility for the velocity is what makes it different to the speed. Speed is only positive.

Explanation:
Answer:
The pressure will be increased
Explanation:
As you move toward the interior of the earth the pressure is going to increase, which will support the column of earth above the person who moves towards the interior.
This column can be calculated by means of the following expression
P = d*g*h
where:
d = density of the earth [ kg/m^3]
g = gravity = 9.81 [m/s^2]
h = column of earth [m]
As we can see the pressure depends on the height or depth as we move into the earth, as well as the density of the Earth.
Answer:
20 degrees
Explanation:
Because projectile has the same range on both angles which on summation gives 90 degrees as a total.
