which is more work pushing with 115N over 15 m or lifting 20N 10meters
Work = Force x Distance
115 x 15 = 1,725
20 x 10 = 200
Obviously pushing 115 N over 15 m
To determine which task requires more work, we need to calculate the work done in each scenario using the formula:
Work = Force x Distance.
Let's calculate the work done in each scenario:
1. Pushing with 115N over 15 meters:
Work = 115N x 15m = 1725 Joules.
2. Lifting 20N over 10 meters:
Work = 20N x 10m = 200 Joules.
Therefore, pushing with 115N over 15 meters requires more work (1725 Joules) compared to lifting 20N over 10 meters (200 Joules).
To determine which requires more work, we need to calculate the work done in both scenarios. Work is defined as the product of force and displacement, given by the equation:
Work = Force * Displacement * cos(theta)
Where theta is the angle between the force and displacement vectors. In this case, we can assume that the force and displacement vectors are in the same direction, so cos(theta) = 1.
Let's calculate the work done in both scenarios:
1. Pushing with 115N over 15 meters:
Work = Force * Displacement
= 115N * 15m
= 1725 Joules
2. Lifting 20N for 10 meters:
Work = Force * Displacement
= 20N * 10m
= 200 Joules
Therefore, pushing with 115N over 15 meters requires more work (1725 Joules) compared to lifting 20N for 10 meters (200 Joules).
