A 6.2 "kilo" bag of sugar is on a counter. How much work is required to put the bag on a shelf a distance of 0.41 m above the counter
m g h = 6.2 * 9.81 * 0.41
= 24.5 Joules
To find the work required to lift the bag of sugar, we can use the formula:
Work = force x distance
In this case, the force is the weight of the bag of sugar and the distance is the height of the shelf.
First, let's convert the weight of the bag from kilograms to Newtons. The weight of an object is given by the formula:
Weight = mass x gravitational acceleration
The mass of the bag is given as 6.2 kilograms. The gravitational acceleration on Earth is approximately 9.8 m/s².
Weight = 6.2 kg x 9.8 m/s² = 60.76 N
Now that we have the weight of the bag, we can calculate the work required to lift it to the shelf.
Work = 60.76 N x 0.41 m = 24.9696 Joules (J)
Therefore, approximately 24.97 Joules of work is required to put the 6.2 kilo bag of sugar on a shelf 0.41 meters above the counter.
