If the spacecraft was traveling at a rate of 2650 m/s when the rockets began to fire and they fire for 633 s, what is the spacecraft’s final velocity?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
