The graph above shows velocity via as a function of time t for a 0.50 kg object traveling along a straight line. the graph has three segments labeled 1,2,and 3.aerobics is a constant force of magnitude FTon an object along its direction of motion the whole time during the segment to only a frictional force of magnitude Ff is also exerted on the object. for another identical object initially at rest no frictional forces exerted during segment two. aerobic starts the same concept force of magnitude FT as in the previous scenario. what is the change in the objects kinetic energy during segment 2?

(A) 3.75 J
(B) 4.00J
(C) 12.0 J
(D) 16.0 J​
