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 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.
