Question

The positions of a particle moving along a straight line are $x_1=50$ m at 10.30 a.m. and $x_2=55$ m at 10.35 a.m. respectively. What is the displacement of the particle between 10.30 a.m. and 10.35 a.m.?

• A. 2 m
• B. 5 m
• C. 7 m
• D. 9 m

Answer 1

The correct option is B 5 m

The positions of a particle moving along a straight line are $x_1=50m$ at 10.30 a.m. and $x_2=55m$ at 10.35 a.m. respectively.

the displacement of the particle between 10.30 a.m. and 10.35 a.m is $x_2-x_1=55-50=5m$
