Question

(a) What are the coordinates of the initial position of the stone? (Hint: Let the student's position be the origin of the coordinate system.)
xi = m
yi = m

(b) What are the components of the initial velocity of the stone?
vix = m/s
viy = m/s

(c) What is the appropriate analysis model for the vertical motion of the stone?
particle under constant, nonzero acceleration
particle under constant speed

(d) What is the appropriate analysis model for the horizontal motion of the stone?
particle under constant, nonzero acceleration
particle under constant speed

(e) Write symbolic

Answer 1

a) If you are the origin and you are holding a stone. What is the initial position?
b) The stone is initially threw to the right. Does it have any velocity in the y-direction?
c) What causes the stone to fall? Does this acceleration ever change?
d) If there is no air-resistance, what forces are acting in the x-direction?
e) Seems we are missing some information here.
