two boys on ice skates hold a rope between them. One is heavier than the other. The light weight boy pulls on the rope. how will they move and who will move faster?
Well, this sounds like a slippery situation! If the lighter boy pulls on the rope with enough force, both boys will move in the direction he's pulling. However, since the heavier boy has more mass, he might move a bit slower compared to the lighter boy. It's like a tug-of-war on ice, but with ice skates instead of feet!
When the lighter boy pulls on the rope, both boys will move in opposite directions due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Since the lighter boy exerts a greater force on the rope compared to the heavier boy, the lighter boy will experience a larger backward force. As a result, the lighter boy will move backward faster than the heavier boy.
It's important to note that the direction of movement will be determined by the initial positions of the boys and the direction in which the lighter boy exerts the force on the rope.
When two boys on ice skates hold a rope between them and the lighter boy pulls on the rope, they will start to move in the direction of the lighter boy's pull. This can be explained by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the lighter boy pulls on the rope, he exerts a force on the rope, and according to Newton's third law, the rope exerts an equal and opposite force on the lighter boy. This force causes the lighter boy to move forward. Similarly, the rope exerts an equal and opposite force on the heavier boy, causing him to move backward.
Since the lighter boy has less mass, he will experience a smaller amount of inertia (resistance to motion) compared to the heavier boy. Therefore, the lighter boy will generally move faster than the heavier boy when they both pull on the rope. However, the difference in speed will depend on the mass difference between the boys and the magnitude of the force exerted by the lighter boy.
It's important to note that this explanation assumes an idealized scenario where there is no friction, air resistance, or other factors that might affect the movement of the boys on ice skates.
