THESE ARE THE ANSWERS 100% TRUST ME
Yes, the answers are correct, but why did you post them?
1. The volleyball accelerates more quickly toward the ground when released from a higher height.
2. The mass of each ball.
3. The balls have the same acceleration.
4. The mass of ball C is greater than the mass of ball A but less than the mass of ball B.
To get the answers to the questions:
1. The correct statement about the volleyball can be determined by understanding the concept of acceleration due to gravity. When an object falls freely, regardless of its mass, it accelerates at the same rate. This means that the volleyball will accelerate the same amount towards the ground each time, regardless of the height it is released from. Therefore, the correct statement is "The volleyball accelerates the same amount toward the ground each time."
2. To calculate the force with which each ball hits the ground, we need to consider the concept of force, which is given by the equation F = m * a, where F is the force, m is the mass, and a is the acceleration. In this case, the acceleration is due to gravity, which is the same for all objects near the surface of the Earth. Therefore, to correctly calculate the force, we need to measure the mass of each ball. Hence, the correct quantity to measure is "the mass of each ball."
3. The statement about the two balls can be determined by the concept of acceleration due to gravity being the same for all objects near the surface of the Moon. This means that both balls will experience the same acceleration and reach the ground at the same time. The weight of an object depends on the gravitational force acting on it, which is different on the Moon compared to Earth. Therefore, the correct statement is "The balls have the same acceleration."
4. To determine the statement about the mass of ball C, we can compare it to the mass and net force of ball A and ball B. In free fall, an object's mass does not affect its acceleration, so the mass of ball C will not be a determining factor. The net force acting on an object can affect its acceleration but does not directly determine its mass. Hence, the mass of ball C cannot be determined from the information provided, so the correct statement is "The mass of ball C cannot be determined from the information provided."
