Answer:
a) , c)
Step-by-step explanation:
Statement A)
From 0.25s to 0.75s
the ball has travelled 3cm
From 0.75s to 1.25s
the ball has travelled 3cm
This means that in 1 second ball has covered 6 cm so in 2 sec it will cover 12 cm.
Statement B)
False
The amplitude of the oscillation is the maximum distance of the object either in positive y axis or negative y axis.
so its is 3 cm.
Statement C)
At 0.75s
Ball is at its highest point
At 1.75
Ball is at its lowest point
so in 1 second the ball travels from its highest point to its lowest point.
Statement D)
False
The ball travel 3cm in 0.5s.
