a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.
Alenkinab [10]

Answer:

t = 9 s

Step-by-step explanation:

A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where

s(t) = -4.9t^2 + 29.4+132.3

We need to find when the stone will hit the ground. It means when s(t) = 0. So,

-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9

So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.

From the picture, we can see that

\sin\theta=\dfrac HB\implies\dfrac{\sin\theta}C=\dfrac H{BC}

\sin\beta=\dfrac HC\implies\dfrac{\sin\beta}B=\dfrac H{BC}

which means

\dfrac{\sin\theta}C=\dfrac{\sin\beta}B
