Q1. A horizontal force of 10 N is applied to the outer edge of a door at an angle of 32° to the door. The width of the door is 0.80 m. The magnitude of the torque of this force on the door with respect to the hinge is most nearly?
Q2. A streetcar named Desire travels between two stations 0.60 km apart. Leaving the first station, it accelerates for 10.0 s at 1.0 m/s2 and then travels at a constant speed until it is near the second station, as it brakes at 2.0 m/s2 in order to stop at the station. How long did this trip take?
Q3. A rocket is launched at an angle of 54° above the horizontal with an initial speed of 96 m/s. It moves for 3 s along its initial line of motion with an acceleration of 30 m/s2. At this time its engines fail and the rocket proceeds to move as a free body. What are the rocket's horizontal range, greatest height, and total time of flight?
