A train moving at 30 m/s brakes with a constant deceleration of 6 m/s squared. What distance does it travel before stopping?
Answer and explanation
Correct answer: B. 75 m
- Step 1: Use v squared = u squared + 2as with v = 0.
- Step 2: s = 900/(2 x 6) = 75 m.
Answer
75 m.
Why not the others: 150 m, 5 m and 37.5 m do not fit.
