Asatellite s travels in a circular orbit around the earth. a rocket is located at the apogee of its elliptical orbit for which  = 0.58. (a) determine the sudden change in speed that must occur at a so that the rocket can enter the satellite’s orbit while in free flight along the blue elliptical trajectory. (b) when it arrives at b, determine the sudden adjustment in speed that must be given to the rocket in order to maintain the circular orbit.

true. the question describes the idea of energy conservation faithfully. energy can change forms but remains the same within an isolated system over time. within such a system, energy cannot be created or destroyed.

answer:

correct answer is which is not any option

solution

in this question we have given,

force on piston 1,=6600n

area of piston 1,=

force on piston 2,=9900n

we have to find area of piston 2, =?

according to pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:

it means,

which becomes

in equation 1

as we know that collision is elastic   so we will have

also we can use momentum conservation

now from above two equations we will have

also we have

so both balls will separate after collision and move in opposite direction as the final velocities are opposite in sign

so correct answer will be

d. the balls separate and move in opposite directions.
