Question: An obiect is thrown upward into the air 10 meters above the ground. The figure above shows the initiaposition of the object and the position at a later time. At time t seconds after the object is thrown upwardthe horizontal distance from the initial position is given by x(t) meters, and the vertical distance from the ground is given by y(t) meters, where ${\frac{d x}{d t}}=1.4$ and ${\frac{d y}{d t}}=4.2-9.8t$,for t $\ge $ 0. Is the angle $\theta $ 1.047? Please answer yes or no.
Answer: no
