A shell is launched at 140 m/s 56.0 degrees above the horizontal. When it has reached its highest point, it launches a projectile at a velocity of 110 m/s 35.0 degrees above the horizontal relative to the shell.

1) Find the maximum height (in m) about the ground that the projectile reaches.

2) Find its distance (in m) from the place where the shell was fired to its landing place when it eventually falls back to the ground.

Solution/explanation, please? Thanks!
