A magnifying glass can be utilized to focus sunlight to a single point. Describe physically and mathematically how this process occurs using:
a) Geometrical ray optics
[Hint: the sunlight can be considered as an object located at infinity]
b) Image formation by lens
[Hint: the sunlight can be mathematically expressed as source of infinite extent, of constant light intensity, given by f(x, y)=a where a is a constant]
A space vehicle is coasting at a constant velocity of 23.5 m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.395 m/s2 in the +x directio..
