building at an angle of 10.1◦
above the horizontal and with an initial speed of 6.74 m/s.
The acceleration of gravity is 9.8 m/s^2.
If the brick is in flight for 2.5 s, how tall is
the building?
Answer in units of m
Homework Equations
x=vix*t
y=viy*t+.5*g*t^2
The Attempt at a Solution
y=viy*t+.5*g*t^2
=(((1/2(9.8m/s^2))2.5s^2)
=30.625m
The answer is incorrect, what have I done wrong in my calculations?
