Concepts Of Physics MCQ Edition [Volume 1]PhysicsRest and Motion Kinematics

A particle starting from rest travels with constant acceleration. If it takes 5.0 s to reach a speed of 18.0 km/h , determine the average velocity during this period in m/s.

Options

A5.0
B2.5
C9.0
D18.0

Correct answer

B. 2.5

Step-by-step solution

Initial velocity, u = 0 Final velocity, v = 18.0 km/h = 18.0 5 18 m/s = 5.0 m/s For constant acceleration, the average velocity is given by: v_ avg = u + v 2 v_ avg = 0 + 5.0 2 = 2.5 m/s
