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
