## Homework Statement

A brick is thrown upward from the top of a

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?
