I am unsure how to solve this physics problem. So, I think I got part A. Although, when it comes to part b and c I am confused. I am particularly confused with b because I know I am supposed to use sin of theta somewhere but I don't know what number I would need to input for that.

A ball is kicked with an initial velocity of 13 m/s in the horizontal direction and 18 m/s in the vertical direction. (Assume the ball is kicked from the ground. For each answer, enter a number.) (a) At what speed (in m/s) does the ball hit the ground? 25.45 m/s (b) For how long (in s) does the ball remain in the air? S (c) What maximum height (in m) is attained by the ball? m
