Suppose a car waiting at red traffic light when the light turns to green the car accelerates uniformly at 2m/s within 6 sec then proceeds moving with a uniform speed at the movement the car starts at the green traffic light a truck passes by heading in the direction with a uniform speed of 10m/s. How long and how far from traffic light the car catches up with the truck?
"0.5at^2+(at)(T-t)=vT"
"0.5(2)(6)^2+(2)(6)(T-6)=10T"
The time will be
"T=18\\ s"The distance:
