NEET Physics Speed & Velocity MCQ Question

Type: MCQ-numerical-Medium-Class 11

A car moves along a straight line with its position at time t given by x(t) = 0.08t^3. What is the average velocity of the car between t = 2.0 s and t = 4.0 s?

A

84 m/s

B

9.60 m/s

C

15.36 m/s

D

25.60 m/s

Correct Answer

Option B

Detailed Explanation

The average velocity is calculated as (x(4.0) - x(2.0)) / (4.0 - 2.0). Substituting the position function, the average velocity is [(0.084.0^3) - (0.082.0^3)] / 2 = 9.60 m/s.
