Question
A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for
420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to:
O 0.20 m/s²
O 0.14 m/s²
O 0.19 m/s²
0.17 m/s²
O 0.16 m/s²
