A 2590-kg test rocket is launched vertically from the launch pad. Its fuel (of negligible mass) provides a thrust force so 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. At the instant of ignition, the rocket has an upward acceleration of 2.00 m/s2 and 1.60 s later an upward velocity of 2.46 m/s . At 4.30 s after...

A small rocket to gather weather data is launched straight up. Several seconds into the flight, its velocity is 100 m/s and it is accelerating at 19 m/s^2. At this instant, the rocket's mass is 47 kg and it is losing mass at the rate of 0.50 kg/s as it bums fuel. What is the net force on the rocket? Express your answer to two significant figures and include the appropriate units.
