Need help solving these two problems

IA boy throws a baseball into a roof and it rolls back down and off the roof with a speed of 4,30 m/s. If the roof is pitched at @. 24. 0 below the horizons the roof edge is 2.90 m above the ground , find the time the baseball spends in the air 3 the horizontal distance from the roof edge to the point where the baseball lands on the ground . A Time baseball speeds in air S BHorizontal distance from roof edge to where the baseball lands on the ground ( in m) m One strategy in a snowball fight is to throw a snowball at a high angle over level ground . Then , while your opponent is watching that snowball, you throw a 2nd one at a low angle timed to arrive befor or at the same time as the First one . Assume both are thrown at a speed of 23.0 m Is The f st one is thrown at an angle of 12.0 with respect to the horizontal, "A What angle should the second snowball be thrown to arrive at the same point as the first ? B) How many seconds later should the End Snowball be thrown after the first in order for both to arrive at the sametime
