What is the maximum acceleration of the wingtips, in m/s^2?(Express your answer in meters per second squared to two significant figures) What is the maximum acceleration of the wing tips, in units of g ?(Express your answer in units of g to two significant figures)

Question 1 When a projectile is at its' maximum height: O The vertical component of velocity is zero O The vertical position is zero The acceleration is zero O The horizontal component of velocity is zero Question 2

The time it takes for a projectile to go up to its' maximum height is the same amount of time that the projectile takes to fall from its' maximum height back down to its initial height. True False

- 5) Ajet plane is flying at constant altitude At time t,=0, it has components of velocity Vx=90 m/s and vy=110 m/s. At time t2=30 s, the components are v,=-170 m/s and Vy=40 m/s. For this time interval, a) find the components of the average acceleration. b) find the magnitude and direction of the average acceleration.
