Answer:
Final velocity, v = 0.28 m/s
Explanation:
Given that,
Mass of the model, 
Speed of the model, 
Mass of another model, 
Initial speed of another model, 
To find,
Final velocity
Solution,
Let V is the final velocity. As both being soft clay, they naturally stick together. It is a case of inelastic collision. Using the conservation of linear momentum to find it as :



V = 0.28 m/s
So, their final velocity is 0.28 m/s. Hence, this is the required solution.
False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.
<span>Newton's third law of motion (also known as lar of action-reaction) states that when an object A exertes a force on another object B, object B also exerts a force on object A equal and opposite to the first force. If we apply the law to this problem, we can say that the force exerted by the car on the horse is equal to the force exerted by the horse on the car, so its magnitude is 60 N.</span>
