A rocket is fired in deep space, where gravity and drag forces are 0. If the rocket has an initial mass of 6000kg, and eject gas at a relative speed of 2000m/s, how much gas must it eject in the first second (1s), to have an inital acceleration of 25m/s?
The puffer fish (tetradontiade) can employ a defense mechanism whereby it fills its stomach with water until the fish is almost spherical in shape. The shape, in conjunction with its external spines, are a significant deterrent to predators. Suppose that a puffer fish takes in water until its mass has increased by f = 1.89 times its initial mass. In this state, and initially at rest, the puffer fish expels the water with a speed s in one direction, while the fish recoils in the opposite direction at a speed v. For this problem neglect the drag-force effects of the surrounding ocean water. Write an expression for v/s in terms of f.
A spaceship’s orbital maneuver requires a speed increase of 1.20 x 10^3 m/s. If its engine has an exhaust speed of 2.50 x 10^3 m/s, determine the required ratio Mi/Mf of its initial mass to its final mass. (The difference Mi - Mf equals the mass of the ejected fuel.)
