A flat car is given an acceleration `a_(0)=2m//s^(2)` starting from rest. A cable is connected to a crate of weight `50kg` as shown whose other end is attached to a fixed support on ground. Neglect friction between the floor and the car wheels and also the mass of the pulley. Calcuollate corresponding tension in th cable if `mu=0.30` between the crate and the floor or the car.
