Answer 1

Given data

*The given force is F = 583 N

*The given distance is s = 1.5 m

*The given time is t = 2.1 s

The formula for the power it takes for a 583 N student to climb up 1.5 m stairs in 2.1 seconds is given as

`P=\frac{F\mathrm{}s}{t}`

Substitute the known values in the above expression as

`\begin{gathered} P=((583)(1.5))/((2.1)) \\ =416.42\text{ W} \end{gathered}`

Hence, the power it takes for a 583 N student to climb up 1.5 m stairs in 2.1 seconds is P = 416.42 W
