A brick is thrown upward from the top of a building at an angle of 40° to the horizontal and with an initial speed of 13 m/s. If the brick is in flight for 3.3 s, how tall is the building?


Expert Answer

Step 1

Let the height of the building is h.

At the initial time, only ...

v=v, sin0
=(13)sin 40°

Image Transcriptionclose

v=v, sin0 =(13)sin 40° 8.35m/s
