1. The problem statement, all variables and given/known data A car initially travelling north at 35 m/s, brakes and turns to avoid an obstacle so that 3 seconds later it is travelling northeast at 20 m/s. Find its average accelera- tion during the period of braking and turning. 2. Relevant equations acceleration=change in velocity/time taken(thank you Chi Meson) 3. The attempt at a solution I got the vector components of the 20m/s vector and got Vx as 10m/s and Vy as 10 root 3 m/s. I don't thinks it's as simple as 15m/s divided by 3s.Any help would be very appreciated.I don't know where to go from here. I'm new here and I'd like to say hello to every member.
