a person rolled a large ball across a field. What information is needed t determine how much work the person did?
Get the weight of the ball and the strength of the person
To determine how much work the person did in rolling a large ball across a field, we need two pieces of information: the force applied by the person to move the ball and the distance the ball traveled.
1. Force: The force applied by the person to roll the ball can be measured in Newtons (N). It represents how much effort was exerted to move the ball. The force can be estimated or measured using a force gauge or by considering the person's strength and effort.
2. Distance: The distance the ball traveled can be measured in meters (m) or any suitable unit of length. It represents how far the ball moved from its initial position to its final position. The distance can be measured using a measuring tape, odometer, or by estimating the distance based on known landmarks.
Once these two pieces of information, force and distance, are known, we can calculate the work done using the following formula:
Work (W) = Force (F) × Distance (d) × Cosine of the angle (θ) between the force and the direction of motion.
By substituting the known values of force and distance into the formula, we can determine the amount of work done by the person in rolling the large ball across the field.
