A particle moves with constant acceleration under the influence of grav- ity. It experiences an acceleration of -9.82 ſ; note that for this question the vertical direction is the y-direction. At time t = 0s the particle is at the origin, and it is moving at a speed of 13" along a vector in the xy plane which makes an angle of 67.4º with the positive x-axis as measured counterclockwise from the x-axis when viewed along the z-axis. 14.
