if the velocity of a ship that moves in a straight line inc
aight line increases from 20 m/s to 30 m/s
calculate the time taken by the ship to cover
this displacement

The time taken by the ship to cover the distance, t = (x/25)  s

Explanation:

Given data,

The initial velocity of the ship, u = 20 m/s

The final velocity of the ship, v = 30 m/s

The average velocity of the ship, V = (20 + 30)/ 2

                                                           = 25 m/s

The distance covered by the ship, d = x m

Then the time taken by the ship to cover the displacement is,

                   d =  V x t

∴                   t = d / V

Substituting the values,

                     t = x / 25

                     t = (x/25)  s

Hence, the time taken by the ship to cover the distance, t = (x/25) s

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

the force on the thing and the distance the force moves the thing
