2. You toss a rock off the top of a building that is 70 m high, throwing it initially in the horizontal direction with a velocity of 13 m/s. a) Fill out the following chart, leaving a "?" for any unknown values at this point. Please note as well that v, and vy at the end of the flight are NOT ZERO. Xo = Yo = y% = Vox = Voy = %3D Vy = Vy = az = %3D %3D t 3D t = b) How long does the rock take to fall before it reaches the ground? Would this time change if it were initially thrown in the same direction with a velocity of 26 m/s? c) How far, in the x- direction, does the rock land away from the building? d) What are the velocities of the rock in thex and y- direction just before it hits the ground? Answers: b) 3.78 s c) 49.1 m d) -37.0 m/s itu is 250 m/s
