1:two cars are moving with a constant speed toward each other and the distance between them is decreasing at a rate of 3 m/s if the two cars are moving with the same speed but this time in the same direction the distance between them is decreasing at a rate 1 m/s. what is the speed of each car 2. Relevant equations : D=VT V=vo+at ? 3. The attempt at a solution: if they have the same speed then when they are moving toward each other each car's speed must be 1.5 m/s but when i read the second part that idea must be invalid Can you please give me a hint on how to start guys?
