Suppose the stone is thrown at an angle of 38.0 below the horizontal from the same building (h = 40.0 m) as in the example above. If it strikes the ground 39.4 m away, find the following. (Hint: For part (a), use the equation for the x-displacement to eliminate vot from the equation for the y-displacement.) (a) the time of flight (b) the initial speed (c) the speed and angle of the velocity vector with respect to the horizontal at impact
