Question

an object is moving in a negative direction with a negative acceleration, for example an object dropped out a window. what does it mean that both velocity and acceleration are negative?
a the object is speeding up.
b the object is slowing down.
c the object will eventually stop.
d the object must be moving downward.

Explanation:

When velocity and acceleration have the same sign (both negative here), the object is speeding up. If they had opposite signs, it would be slowing down. Option B is incorrect (that's for opposite signs). Option C is wrong as acceleration means it won't stop due to that acceleration (e.g., free fall has constant acceleration and speed increases). Option D: The negative direction doesn't have to be downward (it's a coordinate choice), so D is wrong. So A is correct.

Answer:

A. The object is speeding up.
