Power can be calculated using the formula:
\[
\text{Power} = \text{Force} \times \text{Velocity}
\]
In this case, the force applied is \(500 \, \text{N}\) and the constant velocity is \(20 \, \text{m/s}\).
Substituting the values into the formula:
\[
\text{Power} = 500 \, \text{N} \times 20 \, \text{m/s} = 10000 \, \text{W}
\]
So, the power expended on the object is \(10000 \, \text{W}\) (or \(10 \, \text{kW}\)).
\[
\text{Power} = \text{Force} \times \text{Velocity}
\]
In this case, the force applied is \(500 \, \text{N}\) and the constant velocity is \(20 \, \text{m/s}\).
Substituting the values into the formula:
\[
\text{Power} = 500 \, \text{N} \times 20 \, \text{m/s} = 10000 \, \text{W}
\]
So, the power expended on the object is \(10000 \, \text{W}\) (or \(10 \, \text{kW}\)).
