3. The total length of path travelled by an object in motion is called?

A. Displacement

B. Uniform Motion

C. Velocity

D. Distance

Solution

∆x= x final – x initial; where x is displacement; xf (final position) xi (initial position)

xf (final position) = 69.4m

xi (initial position)=16.4m

69.4-16.4 = 53m
