Arocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 44.1m/s^2 . the acceleration period lasts for time 7.00s until the fuel is exhausted. after that, the rocket is in free fall. find the maximum height y_max reached by the rocket. ignore air resistance and assume a constant acceleration due to gravity equal to 9.80 rm{m/s^2} .

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
