You are standing very close to a building that is 15 m high and youthrow a ball upwards from the ground with an initial velocity of 15 m/s. Your friend is on the roof of that building, and throws a second ball downwards with an initial velocity V0,F; your friend throws the ball 0.25 second after you threw yours. Calculate the velocity V0,F of your friend’s ball if the two balls collided at the height of 10 m above the ground. Take g=10m/s2. Science Physics PHYSICS 2
