Question

Velocity - Time graph of a particle is given. Which of the following statement(s) is/are correct.

• A. net displacement is zero
• B. total distance travelled is 80 metre
• C. acceleration of the particle is constant
• D. direction of velocity is constant

Answer 1

The correct option is D direction of velocity is constant

Area under graph = 40m (displacement covered)
Acceleration changes from positive to negative (as it is the slope of the graph).
The velocity however is always positive. This implies that the direction of velocity is always the same.
Option D is correct.
