F = m a
|F| = m |v - vₒ| / t
|F| = m |0 - vₒ| / t
Time taken, t = mvₒ/|F|, where |F| is constant.

For A) t = 1000 × 10 / |F| = 10000/|F|
For B) t = 1000 × 20 / |F| = 20000/|F|
For C) t = 1000 × 30 / |F| = 30000/|F|
For D) t = 3000 × 10 / |F| = 30000/|F|
For E) t = 2000 × 10 / |F| = 20000/|F|
For F) t = 2000 × 20 / |F| = 40000/|F|
For G) t = 2000 × 30 / |F| = 60000/|F|
For H) t = 3000 × 20 / |F| = 60000/|F|

Longest  G = H > F > C = D > B = E > A  Shortest
