A child on a cart with wheels throws a sandbag forward. As a result:a)He moves to the left.b)He moves backward.c)He moves forward.d)He moves to the right.Correct answer is option 'B'. Can you explain this answer?

Question

Answer

The child moves in the backward direction as a consequence of action-reaction law. Sandbag exerts an equal and opposite force in the backward direction.

Answer

Perhaps!! It is due to the 'Inertia of motion' .Since,The Boy throws the sandbag forward .. As a result, His Body Movements Would like To be continued ..Therefore, Due to Inertia of Motion,He moves Backward.

Answer

According to Newton's third law of motion every action has an equal and opposite reaction.... This is why it goes that if the boy throws the bag forward by applying a force the bag will also apply a force on to the boy in the opposite direction resulting in the movement of the boy backward. Thus, B is the correct answer. CHEERS!!

Answer

Explanation:

When the child throws a sandbag forward while sitting on a cart with wheels, the reaction force causes the child and the cart to move in the opposite direction. In this case, the child and the cart will move backward.

Newton's Third Law of Motion:

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. When the child throws the sandbag forward, the sandbag exerts a force on the child in one direction, and the child exerts an equal and opposite force on the sandbag in the opposite direction.

Conservation of Momentum:

The momentum of an object is the product of its mass and velocity. According to the law of conservation of momentum, the total momentum of a system remains constant unless acted upon by an external force. In this case, before the child throws the sandbag, the momentum of the child and the cart is zero since they are at rest.

When the child throws the sandbag forward, the sandbag gains momentum in one direction, and by the law of conservation of momentum, the child and the cart must gain an equal and opposite momentum. Therefore, the child and the cart move backward.

Equal and Opposite Force:

The force exerted by the child on the sandbag is equal in magnitude but opposite in direction to the force exerted by the sandbag on the child. These forces are internal to the system of the child and the cart and do not affect their overall motion. Therefore, the backward movement of the child and the cart is a result of the equal and opposite force exerted by the sandbag.

Conclusion:

In conclusion, when a child on a cart with wheels throws a sandbag forward, the child and the cart move backward due to the equal and opposite reaction force. Therefore, option B, 'He moves backward,' is the correct answer.

Answer

Newton's 3rd law of equation is taking place...which is every action ha it's equal and opposite reaction
