Please help me to solve this physics problem
2. A baseball is thrown straight up with an initial speed of 14.7 m/s from the roof of a building Hp 111.5 m high. (Use the coordinate system shown at the right. Assume the baseball is thrown upward from the edge of the roof, so that it can travel back down to the ground without colliding with the roof. Ignore air resistance. Be sure to include the correct sign and units with...
