The linear speed is $=48.75ms^-1$
The centripetal acceleration is $=31.69ms^-2$
The tangential acceleration is $=17.25ms^-2$

radius is $r=75m$

angular speed is $omega=0.65rads^-1$

angular acceleration is $alpha=0.23rads^-2$

The linear speed is

$v=omega r$

$=0.65*75=48.75ms^-1$

The centripetal acceleration is

$a_c=v^2/r=omega^2r$

$=0.65*0.65*75=31.69ms^-2$

The tangential acceleration is

$a_t=alpha r$

$=0.23*75=17.25ms^-2$
