A skilled gunman always keeps his gun slightly titled above the line of sight while shooting. Why? 11. Assume that a ship is moving at a speed of 56 Kmh-1

one second later. It is said to be moving
at speed of 58Kmh-1. What would be its acceleration?


Because to every action there is equal and opposite reaction ...if the person does not do as mentioned then there may be some injury.

acceleration is rate of change of velocity wrt time.
    a= 58 -  56 *5/18 divided by 1 sec = .55 m/sec .sec
