I need a staight answer, A or B and why
ohaa [14]

Answer:

The answer is A

Step-by-step explanation:

You are not changing -14 into 14, you are just simply saying that you are adding more negative to -14, so instead of saying minus 6, you are saying adding -6. you are still going down on a number line either way.

A blueberry pie is shot out of a pie cannon from a height of 6m and with a velocity of 60 m/s. How many seconds will pass before
sveta [45]

Answer: 1.106 s

Step-by-step explanation:

This situation is related to projectile motion and one the equation that models the height of the blueberry pie in time is:

y=y_{o}+V_{o}sin(\theta) t-\frac{1}{2}gt^{2}

Where:

y=0 m is the blueberry pie final height (when it hits the ground)

y_{o}=6 m is the blueberry pie initial height

V_{o}=60 m/s is the blueberry pie initial velocity

\theta=0 \° is the angle, assuming the pie was shot horizontally

t is the time

g=9.8 m/s^{2} is the acceleration due gravity

Rewriting the equation:

0=y_{o}-\frac{1}{2}gt^{2}

Isolating t:

t=\sqrt{\frac{2y_{o}}{g}}

t=\sqrt{\frac{2(6 m)}{9.8 m/s^{2}}}

Finally:

t=1.106 s
