As the bottle leaves her hand, it is moving at 2. 80m/s. It slides 1. 00m before coming to rest in front of you. (a)draw and name all the forces that act on the bottle while it is in motion. (b)find their magnitudes. The weight is given by the mass/weight rule, Fg = mg = (0. 450)(9. 80) " fg = 4. 41n . Applying the second law to the x-direction, "fx = max # ffr = . The acceleration can be found using the kinematic equation without the time,
