What does -99999 m/s describe?

• Something with a very large, negative velocity (usually meaning moving left)

• Something with a very small, negative velocity (usually meaning moving left)

• Something with a very large, negative acceleration (must be slowing down)

• Something with a very small, negative acceleration (could be slowing down or speeding up)

An object has a velocity of 10m/s and an acceleration of -2m/s/s. If right is the positive direction and left is the negative direction...

• The object is moving to the right and slowing down

• The object is moving to the right and speeding up

• The object is moving to the left and slowing down

• The object is moving to the left and speeding up
