1. A brick is thrown upward from the top of a building at an angle of 25o to the horizontal and with an initial speed of 15 m/s. The brick hits the ground after 3.0 s of flight. (a) Calculate the height of the building. [Label all kinematics charts clearly.] (b) Suggest what kind of building this might be, and whether this brick was thrown by hand or with a brick cannon. Justify your answer as you would to a non-physicist. (c) State the magnitude and direction of the brick’s velocity and acceleration vectors at the instant after the brick was released. Justify your answers. (d) State the magnitude and direction of the brick’s velocity and acceleration vectors at the instant when the brick was at the highest point of its flight. Justify your answers. (e) State the magnitude and direction of the brick’s velocity and acceleration vectors at the instant immediately before the brick hit the ground. Justify your answers.
