question 102

Multiple Choice

A train starts from rest and accelerates uniformly until it has traveled 5.6 km and acquired a forward velocity of $42 \mathrm {~m} / \mathrm { s }$ The train then moves at a constant velocity of $42 \mathrm {~m} / \mathrm { s }$ for 420 s.The train then slows down uniformly at $$0.065 \mathrm {~m} / \mathrm { s } ^ { 2 }$$ until it is brought to a halt.The acceleration during the first 5.6 km of travel is closest to which of the following?

• A)0.16 m/ \(\mathrm { s }^2\)
• B)0.14 m/ \(\mathrm { s }^2\)
• C)0.17 m/ \(\mathrm { s }^2\)
• D)0.19 m/ \(\mathrm { s }^2\)
