If velocity of a particle moving along a straight line changes with time as V(m/s) = 4 sin ( π π /2)t, its average velocity over time interval t = 0 to t = 2(2n − − 1) sec, (n being any +ve integer) is,
A
m/s
B
m/s
C
Zero
D
m/s
Text Solution
Verified by ExpertsThe correct answer is:
A
Displacement over the interval t = 0 to t = 2(2n − − 1) seconds.
= 
= 
⇒ ⇒ average velocity = 
= 
m/s.,
Hence is correct.
