Question

A 2540 kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force such that its vertical velocity as a function of time is given by v(t)=At+Bt2 , where A and B are constants and time is measured from the instant the fuel is ignited. The rocket has an upward acceleration of 1.60 m/s2 at the instant of ignition and, 1.00 s later, an upward velocity of 2.00 m/s Determine A . .
