A 2530-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 + Bt^2 , 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 1.00 m/s^2 and 1.30 s later an upward velocity of 1.70 m/s .

A) Determine A.

B) Determine B.

C) At 3.70 s after fuel ignition, what is the acceleration of the rocket?

  • Shuttle launched on moon and in vacuum

    So, the exhaust gas hitting the launch pad would cause it to accelerate just as fast as the rocket. But as the rocket moves away, not all of the exhaust gas will hit the launch pad, so this effect is limited. A detailed explanation is given.

  • Rocket Physics Launching Force

    Before the launch The gravitational force on the rocket is a constant force pointing down. The only thing that stops the rocket from from moving down is the force exerted on the rocket by the ground (Newton's third law).
