A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
