1. The problem statement, all variables and given/known data Question A car starts from rest and uniformly increases its speed at a rate of 0.7 m/s2 on a circular track of radius R = 253 m. What is the magnitude of the car’s net acceleration after 50 s? acen=.7m/s^2 t=50s R=253m 2. Relevant equations Equations acen=(v^2)/r Maybe? ω=Δθ/Δt a=r(Δω/Δt) 3. The attempt at a solution √[aT^2 + aC^2] aC=.7m/s^2 aT= r(dω/dt) √[.7(253)]=v v=13.308m/s v(50s)=S S=665.4 S/r=θ θ=2.63rad ω=(2.63rad/50s) ω/50=α α=.001052rad/s^2 α(253)=aT aT=.26616 a=√[aT^2 + aC^2] a=.74489m/s^2 Answer is not correct, is there something wrong with my logic?
