Q(b). The ship travels at a constant speed of 4 m/s. When the force due to the tugs is removed, the ship slows down and comes to rest.

       Explain why, initially, the ship travels at a constant speed and then whey it comes to rest.

Q(c). The distance a ship travels before it comes to rest depends on the mass of the cargo in the ship. Suggest and explain how the stopping distance depends on the mass.

A pendulum consists or a metal sphere attached to a thin thread, as shown in Fig. 1.


When the thread is vertical, the metal sphere is at O. The metal sphere is moved from O to X and held in position X by a horizontal force F.
A student determines the time for one complete swing of the pendulum. She uses two methods.
In the first method, she measures the time for one complete swing.
In the second method, she measures the time for 20 complete swings and divides the total time by 20. Explain why the second method gives a more accurate result than the first method.
