Question : The average velocity of the particle from 𝑃 to 𝑄 is 8ms−1 and that from 𝑄 to 𝑆 is 12ms −1 . If 𝑄𝑆 − 𝑃𝑄, then the average velocity from 𝑃 to 𝑆 is
(A) 9.6ms^{-1}
(B) 12.87ms^{-1}
(C) 64ms^{-1}
(D) 327ms^{-1}
Answer : option (A)
Solution :
A particle is moving with uniform acceleration along a straight line. The average velocity of the particle from 𝑃 to 𝑄 is 8ms−1 and that from 𝑄 to 𝑆 is 12ms −1 . If 𝑄𝑆 − 𝑃𝑄, then the average velocity from 𝑃 to 𝑆 is
