1.) A brick is thrown upwardfrom the top of abuilding at an angle of 13.1? above the horizontal andwith aninitial speed of 9.33 m/s. The acceleration ofgravity is 9.8 m/s2 .If the brick is in flightfor 2.9 s,
How tall is the building?2.) An arrow is shot at37? angle withthe horizontal. It has avelocity of 46 m/s.The acceleration ofgravity is 9.8 m/s2 .How highwill the arrowgo? What horizontal distance will ittravel?
