Motion Problems

Question 1

V average when S1 ≠ S2 (S1 = S2)

Answer 1

S1 + S2/t1 + t2

Question 2

V average only when S1 = S2

Answer 2

2 x V1 x V2/V1 + V2

Question 3

Formula for S when S1 = S2

Answer 3

1. When someone goes and comes back by the exact same route
2. When two people are going from the same starting point to the same end point
3. When half of the way was mentioned

V1 x t1 = V2 x t2

Question 4

Formula for S when S1≠S2

Answer 4

1. When they are moving towards one another, but not evenly
2. When they start from the same point, but in opposite directions

S1 + S2 = S
V1 x t1 + V2 x t2 = S
