Answer:
No force is acting between A and B.
Explanation:
It is so because the the object is at rest.
Explanation:
Sure, I can help you with that.
The velocity-time graph of an object of mass m = 50 g is shown in the figure. The graph shows that the velocity of the object is constant from t = 3 s to t = 6 s. This means that the acceleration of the object is zero during this time interval.
According to Newton's second law of motion, F = ma, where F is the force acting on the object, m is the mass of the object, and a is the acceleration of the object. Therefore, if the acceleration of the object is zero, then the force acting on the object must also be zero.
Therefore, there is a time interval from t = 3 s to t = 6 s in which no force acts on the object. This is because the velocity of the object is constant during this time interval, which means that the acceleration of the object is zero.
Here is a step-by-step explanation:
1. The velocity-time graph shows that the velocity of the object is constant from t = 3 s to t = 6 s.
2. This means that the acceleration of the object is zero during this time interval.
3. According to Newton's second law of motion, if the acceleration of the object is zero, then the force acting on the object must also be zero.
4. Therefore, there is a time interval from t = 3 s to t = 6 s in which no force acts on the object.
I hope this helps!
