These two questions re the last on my review and i cant figure out what the answers are or how to get them?

A baseball is thrown at an angle of 22?
relative
to the ground at a speed of 24.3 m/s. The ball
is caught 41.8133 m from the thrower

A.is caught 41.8133 m from the thrower.
The acceleration due to gravity is
9.81 m/s

A.How long is it in the air?
Answer in units of s.
B. How high is the tallest spot in the ball’s path?
Answer in units of m.

2. A shell is fired from the ground with an initial
speed of 1.70 × 103 m/s (approximately five
times the speed of sound) at an initial angle
of 60.0
?
to the horizontal.
The acceleration of gravity is 9.81 m/s

A. Neglecting air resistance, find the shell’s
horizontal range.
Answer in units of m
B.How long is the shell in motion?
