can't get this answer. its from barron ap physics book
a projectile launched at velocity of 125 m/s at angle of 20 deg. a building is 200 m away. at what height above ground wil the projectile strike teh building?
dont you do cos 20 times125 for horiz velocity? but try it onyour calculator? did you get 93.97 like this book? i don't, and they get y component is 34.2 m/s. then they get time of flight 2.128 s. then they get 50.6 for final answer.
help me by explaining and showing work, try it on your calculator and tell me your results. thanks so much, im just stuck.please just show all steps and explain if you got right answer and how
