A constant 6.0N net force acts for 4.0 s on a 12 kg object. what is the objects change of velocity
force*time=change momentum= mass*changevelocity
To determine the object's change in velocity, we can use Newton's second law, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
First, we calculate the acceleration using the following formula:
acceleration = net force / mass
Given that the net force is 6.0 N and the mass is 12 kg, we can substitute these values into the equation:
acceleration = 6.0 N / 12 kg
Simplifying the equation, we find:
acceleration = 0.5 m/s²
Now, we have the acceleration of the object. To find the change in velocity, we use the following equation:
change in velocity = acceleration * time
In this case, the given time is 4.0 s, so we can substitute the values:
change in velocity = 0.5 m/s² * 4.0 s
Evaluating the equation, we find:
change in velocity = 2.0 m/s
Therefore, the object's change in velocity is 2.0 m/s.
