That's for the equation I got from the picture
<span>The solution to the problem is as follows:
W=Fd=mad=425*1.8*66
=50490 J
Therefore, it takes </span><span>50490 J of work the crane will do to accelerate the beam upward at 1.8 m/s^2.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

The cofunction identities for tangent are:
tan (90° – θ) = cot θ and cot (90° – θ) = tan θ
