In a ballistics test, a 28-g bullet pierces a sand bag that is 30 cm thick. If the initial bullet velocity was 55 m/s and it emerged from the sandbag moving at 18 m/s what was the magnitude of the friction force (assuming it to be constant) that the bullet experienced while it traveled through the bag? О 38 N O 1.3 N О 13N O 130 N
