A box (4kg), initially at rest, is pushed by a constant force P along the horizontal rough segment AB (μk=0.3). The box leaves segment AB horizontally and follows a parabolic trajectory, landing at point D after 3 seconds. The box barely clears the obstacle located at point C. Determine: 1. Velocity at B 2. Height of the obstacle 3. Velocity at C 4. Magnitude of velocity at D 5. Force P 3m A 3m B 15 m 200
