# Travel with uniformly accelerated motion

**Classical Mechanics**Level pending

A car goes east at a speed of \( 10 \text{ m/s}.\) Then the car gets into uniformly accelerated motion for just \( 10 \) seconds, and ends up heading back westward at a speed of \( 30 \text{ m/s.} \) What is the distance traveled by the car from the beginning of the acceleration to the moment the speed becomes zero?
