  Transrelativistic supernovae (SNe), which are likely driven by central
engines via jets or winds, have been among candidate sources of
ultrahigh-energy cosmic rays (UHECRs). We investigate acceleration and survival
of UHECR nuclei in the external reverse shock scenario. With composition models
used in Zhang et al. (2018), we calculate spectra of escaping cosmic rays and
secondary neutrinos. If their local rate is $\sim1$% of the core-collapse
supernova rate, the observed UHECR spectrum and composition can be explained
with the total cosmic-ray energy ${\mathcal E}_{\rm cr}\sim10^{51}$ erg. The
maximum energy of UHECR nuclei can reach $\sim 10^{20}-{10}^{21}\rm~eV$. The
diffuse flux of source neutrinos is predicted to be $\sim 10^{-11} -
10^{-10}~{\rm GeV}~{\rm cm}^{-2}~{\rm s}^{-1}~{\rm sr}^{-1}$ in the 0.1-1 EeV
range, satisfying nucleus-survival bounds. The associated cosmogenic neutrino
flux is calculated, and shown to be comparable or even higher than the source
neutrino flux. These ultrahigh-energy neutrinos can be detected by ultimate
detectors such as the Giant Radio Askaryan Neutrino Detector and Probe Of
Extreme Multi-Messenger Astrophysics.
