m The elevator at the space needle starts from rest and accelerates relative to its position according to the following equation a(s)-(-0.085s +3). until it reaches its maximum velocity of 9.05. It stays at S 8² the maximum velocity until deccelerating at the top. An engineering student takes a ball up the elevator and releases it out the window at 41m.

Question
Question 4 m The elevator at the space needle starts from rest and accelerates relative to its position according to the following equation a(s) = (-0.085s +3) until it reaches its maximum velocity of 9.05¹. It stays at $2 s the maximum velocity until deccelerating at the top. An engineering student takes a ball up the elevator and releases it out the window at 41m. e le Animation by Jared Owen used with permission m a. How fast (in)is the elevator (and ball) moving when it is released? b. How high (in meters) will the ball go? c. How long will the ball be in the air before it hits the ground?
