A body of mass 108kg at rest is pushed a distance of 300 m by a force of 72N.calculate the time taken to cover the distance

What is the difference between standing still on trampolin and jumping on trampolin how does spring react in both cases pls explain in easy way Because standing still doesnt provide bounce

How trampolin works ?
when we just stand on it and not jump
Does that happen that springs provide equal and opposite force to body weight and so we remain standing on trampolin but when we jump we provide extra force and springs make us jump pls explain that am i right

Why do axial vectors dont produce motion eg when a bullock cart moves why the wheel does not come out due to axial vector pointing outwards according to right hand rule

When i rotate a slipper on floor it stops after some time so is the reason friction
Because i felt that when rotational motion
Is involved then any other reason would be there for stopping of slipper
