If an object has an initial position

(x_{1}, y_{1}) = (6 m, 8 m), and an initial velocity

(v_{1x}, v_{1y}) = (6 m/s, −6 m/s),what is the final position vector (x_{2}, y_{2})

of the object if its two-dimensional acceleration is described by the graphs in the figure above?

(x_{2}, y_{2}) =
m

------------------------------------------------------------------------

The figure below shows a back view of an adult male and an adult female human (accompanied by two children). (Assume that to the right and up are the positive *x* and *y*directions.)

(a) For a typical male, the vertical distance from the bottom of the feet to the neck is

(b) Repeat the calculation for a typical female with

d_{1} = 145 cm

and the distance from the neck to the hand is
d_{2} = 77 cm.

Find the vector describing the position of the hand relative to the bottom of the feet if the angle at which the arm is held is
θ = 32°

to the vertical.(x,y) =
cm

(b) Repeat the calculation for a typical female with

d_{1} = 133 cm, d_{2} = 63 cm,

and the same angle θ.(x,y) =
cm
