You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward.

a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand?

b. What is the phones initial velocity in the vertical (upward) direction in the instant it leaves your hand?

c. What is the phones final velocity in the vertical (upward) direction in rthe instant before it hits the ground?

d. How long will it take for the phone to hit the ground ?(how much time between just after phone leaves he hand to just before it hits the ground)

e.What is the phones final velocity in the horizontal (forward) direction in the instant before it hits the ground?

f. How far from your feet will your phone be when it hits the ground?

g. What is the magnitude of the final velocity of the phone just before it hits the ground?

h. In what direction is the phone moving just before it hits the ground? Give your answer as an angle in degrees below the forward direction.

(this will be the angle the velocity vector makes with the forward "x " axis)
