What is the final velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?

the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph

What happens when you have unbalanced forces acting on an object?
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
When does an object's velocity change?
When it either accelerates or decelerates
When an object accelerates it is only changing speed but not direction?
No.When an object accelerates its velocity is changing.As velocity is defined as speed with direction, its velocity changes ifeither the speed or the direction of travel changes.As its velocity is changing it is technically accelerating (or possibly 'decelerating'if you are an American)
An object in freefall accelerates at a constant rate of velocity?
No. An object in free-fall accelerates at a constant rate of acceleration.Its speed grows at a constant rate.
When a falling body reaches its terminal velocity its acceleration is?
Terminal velocity means the object no longer accelerates; that means that all forces are in balance, the net force is zero.

What happens to an object's velocity when it accelerates?
"Acceleration" implies that the velocity changes.
When an object accelerates it is only changing speed but not direction?
No.When an object accelerates its velocity is changing.As velocity is defined as speed with direction, its velocity changes ifeither the speed or the direction of travel changes.As its velocity is changing it is technically accelerating (or possibly 'decelerating'if you are an American)
What property changes with time when an object accelerates?
Velocity, and displacement vectors.
When a object accelerates in the same direction as its motion it has?
change in velocity
An object in freefall accelerates at a constant rate of velocity?
No. An object in free-fall accelerates at a constant rate of acceleration.Its speed grows at a constant rate.
When an object is accelerating if its?
An object accelerates if its velocity changes. More precisely, "acceleration" is the rate of change of velocity (how quickly velocity changes), or in symbols, dv/dt.
When a falling body reaches its terminal velocity its acceleration is?
Terminal velocity means the object no longer accelerates; that means that all forces are in balance, the net force is zero.
Does the velocity of an object increase when its falling freely in a vacuum?
It accelerates at a higher rate
What happens as an object falls towards the earth?
It accelerates downward at a rate of 9.8m/s2. Depending on the object and how high above the earth it started, it may reach terminal velocity at which point it will no longer accelerate, but will continue to fall at a constant velocity.
