A cannonball is catapulted toward a castle. The cannonball’s velocity when it leaves the catapult is 51.6 m/s at an angle of 37.
Andrei [34K]

Answer:

v_{y}=35.21m/s

Explanation:

From the exercise we know the cannonball's <u>initial velocity</u>, the <u>angle</u> which its released with respect to the horizontal and its <u>initial height</u>

v_{o}=51.6m/s\\\beta =37.0º\\y_{o}=7m

If we want to know whats the <u>y-component of velocity</u> we need to use the following formula:

v_{y}^2=v_{oy}^2+ag(y-y_{o})

Knowing that g=-9.8m/s^2

v_{y}=\sqrt{((51.6m/s)sin(37))^2-2(9.8m/s^2)(0m-7m)}=35.21m/s

So, the cannonball's y-component of velocity is v_{y}=35.21m/s

a light ray traveling in air enters a second medium and its speed slows to 1.71 × 10^8 meters per second. what is the absolute i
givi [52]
The absolute refractive index is equal to the speed of light of the wave in air divided by the speed of light in the second medium. This means that it is equal to 3 x10^8 / 1.71 x10^8. This means the answer is 1.75
