What is the dimensional formula of strain?

A boy starts at position A, travels 3 kilometres to point B, and then returns to point A. If it takes two hours for this, his speed is

A body starts off at rest and moves in a straight line with a constant acceleration. If its velocity is 8 m/s with a displacement of 32 m, its acceleration is

A body begins at rest and moves for t seconds at 2 m/s² uniform acceleration. If it causes a displacement of 16 m, the time of t is

A body starts from rest. If the body travels with an acceleration of 2 m/s², its displacement after 3 seconds is

A body begins from rest and travels with an acceleration of 2 m/s² . After t seconds the velocity of the body is 10 m/s. Then time, t is

A body begins at rest and accelerates uniformly to cover a distance of 6 metres. If its velocity after the displacement is 6 m/s, then its uniform acceleration a is

 A man throws balls vertically upwards at the same speed, one after the other, with a 2 second interval. What should the throw speed be if more than two balls are in the air at the same time?
