A rocket moves straight upward, starting from rest with an acceleration of +25.5 m/s2. It runs out of fuel at the end of 4.26 s and continues to coast upward, reaching a maximum height before falling back to Earth.
(a) Find the rocket's velocity and position at the end of 4.26 s.
vb = m/s
yb = m

(b) Find the maximum height the rocket reaches.
m

(c) Find the velocity the instant before the rocket crashes on the ground.
m/s
