A Train Starts from Rest and Accelerates Uniformly Until It

Question 133

Multiple Choice

A train starts from rest and accelerates uniformly until it has traveled 5.6 km and acquired a forward velocity of 42 m/s. 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 which of the following?
