A particle moving along a straight line with uniform acceleration has velocities \( 7 \mathrm{~m} / \mathrm{s} \) at A and \( 17 \mathrm{~m} / \mathrm{s} \) at C. B is the mid point of AC. Then
(A) The velocity at B is \( 12 \mathrm{~m} / \mathrm{s} \).
\( \mathrm{P} \)
(B) The average velocity between \( A \) and \( B \) is \( 10 \mathrm{~m} / \mathrm{s} \).
W.
(C) The ratio of the time to go from A to \( \mathrm{B} \) to that from \( \mathrm{B} \) to \( \mathrm{C} \) is \( 3: 2 \).
(D) The average velocity between B and C is \( 15 \mathrm{~m} / \mathrm{s} \).
