The figure shows a two-ended “rocket” that is initially stationary on a frictionless floor, with its center at the origin of an x axis. The rocket consists of a central block C (of mass M = 6.10 kg) and blocks L and R (each of mass m = 2.70 kg) on the left and right sides. Small explosions can shoot either of the side blocks away from block C and along the x axis. Here is the sequence: (1) At time t = 0, block L is shot to the left with a speed of 2.60 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at time t = 0.90 s, block R is shot to the right with a speed of 2.60 m/s relative to the velocity that block C then has (after the second explosion). At t = 3.50 s, what are (a) the velocity of block C (including sign) and (b) the position of its center?

A rocket, which is in deep space and initially at rest relative to an inertial reference frame, has a mass of 85.2 x 105 kg, of which 18.3 x 105 kg is fuel. The rocket engine is then fired for 170 s, during which fuel is consumed at the rate of 360 kg/s. The speed of the exhaust products relative to the rocket is 2.60 km/s. (a) What is the rocket's thrust? After the 170 s firing, what are (b)...

A rocket accelerates by burning its onboard fuel, so its mass decreases with time. Suppose the initial mass of the rocket at liftoff (including its fuel) is m, the fuel is consumed at rate r, and the exhaust gases are ejected with constant velocity v_e (relative to the rocket). A model for the velocity of the rocket at time t is given by the equation v(t) = -gt - v_e ln m - rt/m where g is the acceleration due...
