1. The problem statement, all variables and given/known data For the first half of a straightly travelled path which is α=60° from some reference line, a body is moving with a velocity of v1=72 km/h. During the second half of a straightly travelled path, the body is moving with an angle of β=30° with a velocity of v2=36 km/h.What is the average velocity? 2. Relevant equations All translational kinematic. 3. The attempt at a solution So first of all I've calculated x and y components of the both velocities. Then, I've found average component velocities of the resultant average velocity needed (I've done this bearing in mind that the body is moving with one velocity for the half of the total path, and with another velocity for the second half of the total path). I've obtained the average velocity as 43.55 km/h, however the answer in the says that the average velocity would be 46.3 km/h. So if you could solve the problem yourself and tell me what you get as the result.
