distance

Spheres of unit diameter are centered at (l, m, n) where l, m, and n take every possible integer values. The distance between two spheres is computed from the center of one sphere...

A surveyor has to measure the horizontal distance from her position to a distant reference point C. Using her position as the center, a 200 m horizontal line segment is drawn with...

A particle, starting from origin at $$t=0$$ $$s,$$ is traveling along $$x$$-axis with velocity $$v = {\pi \over 2}\cos \left( {{\pi \over 2}t} \right)m/s$$ At $$t=3$$ $$s,$$ the di...
