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 having an initial weight of 3000 lb (including 2400 lb of fuel), and initially at rest, is launched vertically upward. The rocket burns fuel at a constant rate of 80 lbs, which provides a constant thrust, T, of 8000 lb. The instantaneous weight of the rocket is w(t) = 3000 - 80t lb. The drag force, D, experienced by the rocket is given by D = 0.005g(dy/dt)^2 lb, where y is distance in ft, and g =...

Need help in solving this problem a 2220-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 1.20 m/s2 and 1.80 s later an upward velocity of 1.64...

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

Student Activity 9 A 30 kg rocket toy lifts off vertically from the ground. After 3 minutes, its engine stops. The rocket has then a speed of 320 m/s and is at an altitude of 2600 m. a) What is the work done by the rocket engine? b) What is the average power of the rocket engine? (Actually, the mass of the rocket decreases as fuel is ejected, but we will proceed as if the mass remains constant.)
