RELATIVE VELOCITIES IN ONE-DIMENSION А. A car passes station A with a velocity of 60kph, East. At the same time, a motorcycle passes the same station with a velocity of 30 khp, West. Find the speed at which they are moving away from each other. A cheetah with a speed of 120kph is chasing a gazelle that is running away with a speed of 70kph. If they are 50 meters apart, how long does it take for the cheetah to chase its prey? В.
