Could i please get some assistance with these multiple choice questions ? Thanks

Question 1 You are standing on top of a 207 m tall building. A drone operated by your friend is headed straight down, at a speed of 27.0 m/s. Just as the drone passes you, you release a tennis ball off the roof. How fast is the ball going when it passes the drone? Question 2 Spacex plans to transport humans to Mars, but experienced a few rocket failures while on initial tests. So suppose the rocket to Mars (without people on board - another test flight) liftoffs from earth, from rest, with an acceleration of 50.5 m/s. Unfortunately, after 8.85 s, the rocket experiences a failure and shuts off. It then continues to coast upward (with no appreciable air resistance). What is the maximum height the rocket reaches above the surface
