NEET Physics Speed & Velocity MCQ Question
Type: MCQ-numerical-Hard-Class 11
An object moves along a straight line with its velocity given by v(t) = 5t m/s, where t is in seconds. Calculate the average velocity of the object between t = 0 s and t = 4 s.
A
10 m/s
B
5 m/s
C
15 m/s
D
20 m/s
Correct Answer
Option A
Detailed Explanation
The average velocity is calculated as the change in displacement over the change in time. Using v(t) = 5t, displacement at t = 4 s is 40 m and at t = 0 s is 0 m, giving an average velocity of (40 - 0) / (4 - 0) = 10 m/s.
