Question: If $ x=at+bt^{2} $ , where x is the distance travelled by the body in kilometers while t is the time in seconds, then the unit of & is
Options:
A) km/s
B) $ kms $
C) $ km/s^{2} $
D) $ kms^{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ [x]=[bt^{2}] $ .
Hence $ [b]=[x/t^{2}]=km/s^{2} $
