Four people mow a lawn in the table below. Who does the most work? (Work = Force * displacement)
Person Force (N) Displacement (m) Time (s)
1 2 10 10
2 10 2 20
3 2 5 10
4 5 2 20
A- Person 1
B- Person 2
C- Person 3
D- Person 4
E- Person 1 and 2 do the same amount of work
F- Person 3 and 4 do the same amount of work
To calculate the work done by each person, we use the formula Work = Force * displacement.
Person 1: 2 N * 10 m = 20 Nm
Person 2: 10 N * 2 m = 20 Nm
Person 3: 2 N * 5 m = 10 Nm
Person 4: 5 N * 2 m = 10 Nm
Therefore, Person 1 and Person 2 both do the most work, with 20 Nm each. The answer is E - Person 1 and 2 do the same amount of work.
To determine who does the most work, we need to calculate the work done by each person using the formula Work = Force * Displacement.
For Person 1, the work done is 2 N * 10 m = 20 N*m.
For Person 2, the work done is 10 N * 2 m = 20 N*m.
For Person 3, the work done is 2 N * 5 m = 10 N*m.
For Person 4, the work done is 5 N * 2 m = 10 N*m.
Since Person 1 and Person 2 both do the same amount of work, the correct answer is E- Person 1 and 2 do the same amount of work.
