3 4 A person stands on the edge of a sea cliff. The person throws a stone vertically upwards. Air resistance acting on the stone can be ignored. The stone eventually hits the sea. Which velocity–time graph best shows the motion of the stone from when it is released until it hits the sea? A B C D 5 An object starts from rest at time t = 0 and moves in a horizontal line. The graph shows how the velocity v of the object varies with time. What is the distance travelled by the object during the time that its acceleration is zero?
