A roofing shingle elevator is lifting a 30.0-kg package to the top of a building at constant speed. The angle between the elevator track and the horizontal is 75∘. The power of the elevator is 800 W. Part A Determine the vertical component of the speed with which the package is moving up. Assume no friction is exerted by the incline surface on the package.
