Consider conservation of momentum.solars said:Two children are facing each other. Child one has mass of 45kg and the other 65 kg. They push off one another and move in opposite directions. What is the ratio of child one's speed to child 2's?
Answer choices:
a 45:65
b 45:110
c 1:1
d 65:45
e can't tell from this info
I don't know where to start, so I'm thinking the answer is e.
The speed ratio of two objects with different masses is determined by the ratio of their masses. In the case of two children, the speed ratio would be the ratio of their masses. For example, if one child has a mass of 50 kg and the other has a mass of 25 kg, the speed ratio would be 50:25 or 2:1.
The speed ratio determines how fast each child will move. The child with the lower mass will move faster than the child with the higher mass. This is because the force required to move an object is directly proportional to its mass. Therefore, the child with the lower mass will require less force to move and will move faster.
The speed ratio and force have an inverse relationship. This means that as the speed ratio increases, the force required to move the objects decreases. In the case of two children with different masses, the child with the lower mass will have a higher speed ratio and will require less force to move.
Yes, it is possible for the speed ratio of two children with different masses to be equal. This would occur if the children have the same mass or if the ratio of their masses is equal. For example, if one child has a mass of 50 kg and the other has a mass of 100 kg, the speed ratio would be 50:100 or 1:2, which is equal.
The speed ratio does not directly affect the acceleration of the children. Acceleration is determined by the net force applied to an object, which is affected by factors such as friction, air resistance, and the force applied by the children. However, the speed ratio can indirectly affect acceleration, as the child with the lower mass will require less force to move and therefore may accelerate faster than the child with the higher mass.
