A flat car is given an acceleration \( a_{0}=2 \mathrm{~m} / \mathrm{s}^{2} \) starting from rest. A cable is connected to a crate \( A \) of weight \( 50 \mathrm{~kg} \) as shown. Neglect friction between the floor and the car wheels. Also the mass of the pulley is negligible. If coefficient of static friction is \( \mu=0.30 \) between the crate and the floor of the car, then the tension in the cable is
(a) \( 350 \mathrm{~N} \)
(b) \( 250 \mathrm{~N} \)
(c) \( 300 \mathrm{~N} \)
(d) \( 400 \mathrm{~N} \)
