Suppose the stone is thrown at an angle of 30.0° below the horizontal from the same building (h = 45.0 m) as in the example above. If it strikes the ground 57 m away, find the following. (Hint: For part (a), use the equation for the x-displacement to eliminate v0t from the equation for the y-displacement.) 

(a) the time of flight s 

(b) the initial speed m/s 

(c) the speed and angle of the velocity vector with respect to the horizontal at impact speed m/s angle ° below the horizontal
