A 2540 kg test rocket is launched vertically from thelaunch pad. Its fuel (of negligible mass) provides a thrust force such thatits vertical velocity as a function of time is given by v1t2 = At + Bt2,where A and B are constants and time is measured from the instant thefuel is ignited. The rocket has an upward acceleration of 1.50 m/s2 atthe instant of ignition and, 1.00 s later, an upward velocity of 2.00 m/s. Determine A and B, including their SI units.
