For a straight trajectory of a particle instantaneous velocity is
Correct answer: B. average velocity
- A. 2*(average velocity)
- B. average velocity
- C. zero
- D. not enough info
Explanation
Explanation As it is along a straight path, the distance travelled by the particle will be equal to the displacement of the particle. Also, the direction of the particle is always directed towards the instantaneous velocity of the particle, which tells us that the direction of motion is uniform.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
