Drew used a horseshoe with more mass and threw with less force than Blake.
Drew used a horseshoe with more mass and threw with less force than Blake.
Drew used a horseshoe with more mass and threw with the same force as Blake.
Drew used a horseshoe with more mass and threw with the same force as Blake.
The horseshoes have the same mass, but Drew threw with less force than Blake.

The other option is: a runner slowing down at the end of a race.
The statement best explaining the results of Blake and Drew playing horseshoes is: "The horseshoes have the same mass, but Drew threw with more force than Blake."
In the scenario of four movers picking up boxes, the box that will have the greatest acceleration is: "a 10 kg box lifted with 60 N of force."
The amount of force the pitcher applied to the baseball is: "11.6 N."
The situation that describes a negative acceleration is: "a runner slowing down at the end of a race."
To check your answers and understand the reasoning behind them, let's go through each question step by step:
1. Blake and Drew are playing horseshoes. Blake's horseshoe lands three-fourths of the way to the target, while Drew's horseshoe lands past the target. The question asks which statement best explains the results. The correct answer is "The horseshoes have the same mass, but Drew threw with more force than Blake." The reasoning is that since Drew's horseshoe landed past the target, it means he threw it with more force than Blake, even though they have the same mass.
2. Four movers pick up boxes of different masses and apply different amounts of force to lift them. The question asks which box will have the greatest acceleration. The correct answer is "a 10 kg box lifted with 60 N of force." The reasoning is that according to Newton's second law, acceleration is directly proportional to the force applied and inversely proportional to the mass. So, with the same force applied, a box with less mass will have a greater acceleration.
3. A baseball has a mass of 145 g, and a pitcher throws it with an acceleration of 80 m/s^2. The question asks how much force the pitcher applied to the baseball. The correct answer is "11.6 N." To find the force, we use Newton's second law, F = m x a, where F is force, m is mass, and a is acceleration. Converting the mass from grams to kilograms (145 g = 0.145 kg), we multiply it by the acceleration to get the force: F = 0.145 kg x 80 m/s^2 = 11.6 N.
4. The question asks which situation describes a negative acceleration. The correct answer is "a runner slowing down at the end of a race." Negative acceleration, also known as deceleration, occurs when an object's velocity decreases over time. In this scenario, the runner is slowing down, meaning their velocity is decreasing, which corresponds to a negative acceleration.
I hope this explanation helps you understand the reasoning behind each answer choice and confirms whether your selections were correct.
