a hot air balloon is descending at a constant 6 m/s when you throw your iPhone horizontally with an initial 8 m/s. Find the magnitude and the direction of your phones velocity. Find the horizontal component of your phone's velocity just before it hits the ground?

Question

anonymous · Answer

you have two velocities in different directions. This means you must use the component displacement equations

|dw:1359932956741:dw|

|dw:1359933013697:dw|

anonymous · Answer

using Pythagorean theorem, you get

$$v_0^2=6^2+8^2$$

$$v_0=\sqrt{36+64}=\sqrt{100}=10$$

so this is th magnitude of the initial velocity of the phone

anonymous · Answer

Use the trig functions to find the direction... you know the the sides and are looking for theta

lastly I believe there is missing information for the last question
