To solve this problem, we need to use the formula for work done in lifting an object:<br /><br />Work = Force × Distance<br /><br />Given information:<br />- Work done = 2.0 J<br />- Mass of the apple = 180 g = 0.18 kg<br /><br />First, we need to calculate the force required to lift the apple. The force required is equal to the weight of the apple, which is the product of its mass and the acceleration due to gravity.<br /><br />Force = Mass × Acceleration due to gravity<br />Force = 0.18 kg × 9.8 m/s²<br />Force = 1.764 N<br /><br />Now, we can use the work formula to find the distance the apple was lifted.<br /><br />Work = Force × Distance<br />2.0 J = 1.764 N × Distance<br />Distance = 2.0 J / 1.764 N<br />Distance = 1.13 m<br /><br />Therefore, the apple was lifted a distance of 1.13 meters.
