Anything less dense than water will float, like oil. Anything more dense than water will sink, like rock.
Question is from B to C
Answer: (b) 1.5m/s
x1=3m, x2=9m
t1=1s, t2=5s
Displacement, ∆x=(9-3)m=6m
Time elapsed, ∆t=(5-1)s=4s
So average velocity v =∆x/∆t=6/4=1.5m/s
Force moves the object but if the same anyone force is applied to both sides then it doesn’t move
