Q: Bryn fires a piano from a cannon with a muzzle velocity ($$v_o$$) of 26 m/s at an angle of 10 degrees giving it a $$v_{oy}$$ of 4.51 m/s. To find the times for which the height of the object is zero, we may use the equation

$$d_y=v_{oy}t+\frac{1}{2}gt^2$$

we can substitute

$$d_y=0$$ and

$$v_{oy}=4.5$$

to give:

$$0=4.5t+\frac{1}{2}(-9.8)t^2$$

And then factor t from both terms to give

$$0 = t(4.5+\frac{1}{2}\cdot(-9.8)t)$$.

The equation will give a zero value for two values of t. Without simplification, what two values of t will solve the equation?
