A book starts at rest. If Fa=20.0 N, the mass of the book is 3.00 kg, θ=30º and d = 6.2 m, determine the speed of the book at the end of the displacement. Use g = 10 Kg/m. Hint: Determine the net force (applied force net gravity) in the direction of displacement and then multiply by the displacement. Use the work energy theorem to get speed.
