When car is moving on a horizontal icy floor, if its brakes are locked,wheels stops rotating and starts liding. What happens to rotational kinetic energy ?

A simple pendulum is suspended from the ceiling of a car and its period of oscillation is T when the car is at rest. The car starts moving on a horizontal road with a constant acceleration g (equal to the acceleration due to gravity, in magnitude) in the forward direction. To keep the time period same, the length of th pendulum
