Kailina has a 150 pound box of red vines (68 kg) and Michelle wants them! One day, while over at Kailina's watching the Princess Collection on Disney+, when Kailina leaves the room to answer a phone call Michelle quickly finds the box and begins to push it out the front door. If Michelle pushes with a force of 800 N at an angle of 30 degrees below the horizontal what will be the acceleration of Kailina's box of red vines? (the coefficient of friction between the box and the floor is 0.6)
