The image shows a rocket sled. In the top image all four forward thrusters are engaged, creating a total forward thrust of magnitude 4T , where T= 803 N. In the bottom image, in addition to the four forward thrusters, one reverse thruster is engaged, creating a reverse thrust of magnitude T . In both cases a backward force (friction and air drag) of magnitude f= 221 N acts on the sled. show answer No Attempt What is the ratio of the greater acceleration to the lesser acceleration
