Hmmmm, you either tell your parent, try to fix it, or blame it on the dog with a baseball bat that always comes on your yard and tries to eat you.

(6-16)/4.0=-2.5 m/s²
Acceleration of the car is -2.5 m/s²
-- The object's weight is different on each planet, while it is
apparently weightless during the trips in between.
-- On some if not all of the three planets, the object needs to be
surrounded by protection from heat, cold, poisonous gases, or
solar radiation.
-- If the object is any kind of life form, then its circadian rhythm is
all screwed up, and it is having trouble sleeping.
-- The object has accumulated a huge balance of frequent flier miles.
Answer:
When an object changes speed (increases/decreases) it results in acceleration/de acceleration, its velocity also changes.
Explanation:
Acceleration is the rate of change in velocity.An object can accelerate when speed increases, decreases or direction changes. All these instances involves a change in velocity.Velocity is a vector quantity thus it has magnitude and the direction.Acceleration due to change in direction is centripetal acceleration.The expression for finding acceleration is;
a=change in velocity/change in time
a=Δv/Δt in m/s²
