A ship is starting its voyage from Muscat to Salalah. After leaving the Muscat port it gains an average speed of 45km/h in 2 hours. It then continues its journey with the same speed for next 16 hours. After 16 hours it reduces the speed and finally stopped at Duqm port in 1hour.

a) Plot the speed time graph for the whole journey of the ship. (use graph paper for this part)
b) Calculate the initial acceleration and final acceleration of the ship in km/h2.        

            c)   Estimate the total distance travelled by the ship from Muscat to Duqm.          

            d)   Plot the distance time graph for the whole journey of the ship. (use graph paper for this part)
