Replying to I need a physicist

 
A rock is thrown straight upward with an initial velocity of 9.6 m/s in a location where the acceleration due to gravity has a magnitude of 9.81 m/s2. To what height does it rise?


and


 
A small airplane flies at a velocity of 145 km/h toward the south as observed by a person on the ground. The airplane pilot measures an air velocity of 172 km/h south. What is the velocity of the wind that affects the plane?


if someone knows how to do either of those it'd be very appreciated...if i'm asking too much here let me know cuz i have NO idea how much even needs to be done to solve either of those
