8 s, how tall is the building?0 = yo + (13)(sin35)(2.8) + (1/2)(-9.81)(2.yo = 17.......

A brick is thrown upward from the top of a building at an angle of 35° to the horizontal and with an initial speed of 13 m/s. If the brick is in flight for 2.8 s, how tall is the building?

_____m

Thanks :D

-

y = yo + Vo(t) + (1/2)(a)(t^2)
0 = yo + (13)(sin35)(2.8) + (1/2)(-9.81)(2.8)^2
yo = 17.5 m <-- Answer
