Astudent throws a rock into the sky from the top of the webster build- ing with an angle α = π 4 from the horizontal line and the initial velocity 1 is 10 meters per second. the building is 100 meters tall from the ground. suppose there is only the gravitational force acting on it with the gravita- tional acceleration g = 9.8m/s 2 . suppose we choose the horizontal ground surface as x-axis and vertical line above the bullet position as y-axis. let r(t) =< x(t), y(t) > be the position function for the bullet at time t > 0. find the initial position r(0) =< xo, yo > and the initial velocity r'(0) =< uo, vo >
