1. The problem statement, all variables and given/known data A short track speed skaer is making a turn at one end an ice rink, increasing his speed frm uniformly 10 m/s t 20 m/s in two seconds. The radius of the turn is 5 meters. While he is in the middle of the turn, and mving at 15 m/s, what is a. tangential acceleration b. centripetal acceleration c. magnitude of his acceleration 2. Relevant equations v^2/r magnitude of a = sqrt((tangential)^2+(centripetal)^2) 3. The attempt at a solution tangential= 15 m/s centripetal=(15m/s)^2/(5m)=45m/s^2 magnitude of acceleration = sqrt((15)^2+(45)^2)=47.43 Please help me out here.
