Calculate the power output of a 1.8-g spider(the black dot) as it walks up a windowpane at 2.3 cm/s. The spider walks on a path that is at [tex]25^{o}[/tex] to the vertical as illustrated below.

2. Relevant equations

P = W/t

F = mg

3. The attempt at a solution

P= W/t = Fd/t = Fv cos [tex]\theta[/tex] = mgv cos 25 = (0.0018 kg)(9.81 m/s^2)(0.023 m/s) cos25 = 0.00037 W.

Is this correct?

Thanks
