Here is the problem I am working on. I have found answers for all of them except part (f), which is the one I need help with. I will report the answers I have so far: A classic 1957 Chevrolet Corvette of mass 1240 kg starts from rest and speeds up with a constant tangential acceleration of 2.00 m/s^2 on a circular test track of radius 60.0 m. Treat the car as a particle. (a) What is its angular acceleration? --> 0.0333 rad/s2 (b) What is its angular speed 6.00 s after it starts? --> 0.2 rad/s (c) What is its radial acceleration at this time? --> 2.4 rad/s2 (d) (I'll skip this one, since it's just a sketching problem) (e) What are the magnitudes of the total acceleration and net force for the car at this time? --> atot = 3.12 m/s2 and ΣF = 3874 N (f) What angle do the total acceleration and net force make with the car's velocity at this time? I'm wondering if I should use one of the rotational kinematics equations, but I'm still not sure how to go about it. Any ideas would be helpful. Thank you!
