A student is demonstrating acceleration by throwing two balls. She throws both balls using the same amount of force in the same direction. The first ball she throws has a mass of 0.25 kg and the second ball has a mass of 0.5 kg. Explain what will happen to their acceleration and why. (1 point) Responses The first ball has a smaller mass, so it will have greater acceleration than the second ball. The first ball has a smaller mass, so it will have greater acceleration than the second ball. The first ball has a smaller mass, so it will have less acceleration than the second ball. The first ball has a smaller mass, so it will have less acceleration than the second ball. The balls have equal acceleration because they are being thrown in the same direction. The balls have equal acceleration because they are being thrown in the same direction. The balls will have equal acceleration because they are being thrown with the same force. The balls will have equal acceleration because they are being thrown with the same force. Skip to navigation page 13 of 13
The correct answer is: The first ball has a smaller mass, so it will have greater acceleration than the second ball.
This is because the acceleration of an object is inversely proportional to its mass. Therefore, a smaller mass will result in a greater acceleration when the same force is applied.
What change would increase the acceleration of the dog sled? (1 point) Responses add more mass to the sled add more mass to the sled add another dog to the sled add another dog to the sled run the sled up a hill run the sled up a hill remove a dog from the sled remove a dog from the sled Skip to navigation page 13 of 13
I apologize for the incorrect response. You are correct, removing a dog from the sled would actually decrease the acceleration of the dog sled. According to Newton's second law of motion (F = ma), when force is constant, increasing mass will result in a decrease in acceleration. Therefore, the correct answer is to add another dog to the sled.
which object will accelerate more if the student exerts an equal amount of force on each object? (1 point) responses 10 kg box 10 kg box two 10 kg boxes two 10 kg boxes
The correct answer is: two 10 kg boxes.
If the student exerts an equal amount of force on each object, the acceleration will depend on the mass of each object. Since the two 10 kg boxes have a larger total mass compared to the single 10 kg box, they will experience less acceleration.
What change would increase the acceleration of the dog sled? (1 point) Responses
Decreasing the mass of the dog sled or increasing the applied force will increase the acceleration of the dog sled.
is that correct?
Ben and Peter are playing horseshoes. Ben takes the first turn, and his horseshoe lands three-fourths of the way to the target. Peter takes the next turn, and his horseshoe lands past the target. Which statement best explains the results?(1 point) Responses The horseshoes have the same mass, but Peter threw with less force than Ben. The horseshoes have the same mass, but Peter threw with less force than Ben. Peter used a horseshoe with more mass and threw with the same force as Ben. Peter used a horseshoe with more mass and threw with the same force as Ben. Peter used a horseshoe with more mass and threw with less force than Ben. Peter used a horseshoe with more mass and threw with less force than Ben. The horseshoes have the same mass, but Peter threw with more force than Peter.
The correct answer is: Peter used a horseshoe with more mass and threw with less force than Ben.
This explanation aligns with the given information. Ben's horseshoe landed three-fourths of the way to the target, indicating that Ben applied a sufficient amount of force to propel the horseshoe a significant distance. On the other hand, Peter's horseshoe landed past the target, suggesting that Peter either applied less force or used a heavier horseshoe. Since it is stated that the two horseshoes have the same mass, the most reasonable explanation is that Peter used a horseshoe with more mass and threw with less force than Ben.
