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.


What will always change when an object accelerates?

The object's velocity will change when it accelerates. Acceleration is the rate of change of velocity, so as an object accelerates, its velocity will continuously increase or decrease depending on the direction of acceleration.


How does an objects velocity change when an object accelerates?

When an object accelerates, its velocity changes by either increasing or decreasing, depending on the direction of the acceleration. If the object is speeding up, its velocity will increase; if it is slowing down, its velocity will decrease. The rate of change in velocity is directly proportional to the magnitude of the acceleration.


If an object is accelerating how does its kinetic energy change?

The kinetic energy of an object increases as it accelerates. This is because kinetic energy is directly proportional to the square of the object's velocity. As the object accelerates, its velocity increases, resulting in a greater kinetic energy.


What is acceleration and what atr two conditions that can change when an object accelerates?

Acceleration is the rate at which the velocity of an object changes over time. Two conditions that can change when an object accelerates are its speed (magnitude of velocity) and direction of motion.

What happens to an object's velocity when it accelerates?

"Acceleration" implies that the velocity changes.


When an object accelerates what about its motion changes?

When an object accelerates, its velocity changes. This can mean either speeding up, slowing down, or changing direction. The rate at which its velocity changes is determined by the magnitude of the acceleration.


What property changes with time when an object accelerates?

Velocity, and displacement vectors.


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.


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.
