Accelerate 6kg & 4kg Blocks: Instantaneous Force of 60N

In summary, the conversation discussed the problem of two blocks connected by a rope and resting on a frictionless floor. The question asked was about the acceleration of the blocks when a 60N force is applied to the 6kg block for one second. It was also mentioned that the acceleration will depend on the direction of the force, and if it is away from the 4kg block, the acceleration will be the same for both blocks.

Hello friends
I have a problem.please give me the answer.
Two blocks of masses 6kg and 4kg connected by a rope are resting on frictionless floor.If an instantaneous force of 60N is applied to 6kg block for only a second.Then what is the acceleration of the first and second block.Is the acceleration of first and second box same or different and why?please reply me .[The force applied is parallel to the rope in between 6kg and 4 kg and pulls the blocks]

The acceleration will depend on the direction of the force.
if it is in the direction away from the 4kg block then the acceleration will be the same.
 

1. What is meant by "accelerate" in this context?

"Accelerate" refers to the rate of change in velocity of an object. In this case, it specifically refers to the increase in speed of the 6kg and 4kg blocks.

2. How is the force of 60N calculated?

The force of 60N is calculated using Newton's Second Law, which states that force (F) equals mass (m) times acceleration (a). In this case, the force is equal to the mass of the blocks (6kg and 4kg) multiplied by their acceleration.

3. What is the significance of the blocks being 6kg and 4kg?

The mass of an object affects its resistance to acceleration. Heavier objects, such as the 6kg block, require more force to accelerate compared to lighter objects, like the 4kg block. Thus, the difference in mass between the two blocks affects the amount of force needed to accelerate them.

4. What is the difference between acceleration and instantaneous force?

Acceleration refers to the rate of change in velocity, while instantaneous force refers to the force exerted on an object at a specific moment in time. In this case, the acceleration of the blocks is caused by the instantaneous force of 60N.

5. How does changing the force or mass impact the acceleration of the blocks?

According to Newton's Second Law, the acceleration of an object is directly proportional to the force applied and inversely proportional to its mass. This means that increasing the force or decreasing the mass will result in a greater acceleration of the blocks.
