Base your answers to questions 87 through 93 on the information and diagram below. A 10.0-kilogram box starts from rest at point A and is accelerated uniformly to point B in 4.0 seconds by the application of a constant horizontal force F. At point B, the speed of the box is 10.0 meters per second as it begins to move up a plane inclined at 30.° to the horizontal. [Neglect friction.] 0 m/s 10.0 kg 10.0 m/s 0= 30.° A B at 90. Calculate the magnitude of the impulse that would be required to stop the box at point B. 91. As the box moves up the incline, what happens to its speed and gravitational potential energy with respect to AB? (1) Both speed and gravitational potential energy decrease. (2) Speed decreases and gravitational potential energy increases. (3) Speed remains the same and gravitational potential energy decreases. (4) Speed remains the same and gravitational potential energy increases. Topic Chergy
