A particle moving along a straight line with uniform acceleration has velocities 7 m/s at P and 17 m/s at Q. R is the midpoint of PQ. Then
- the average velocity between R and Q is 15 m/s
- the ratio of time to go from P to R and that from R to Q is 3: 2
- the velocity at R is 10 m/s
- the average velocity between P and R is 10 m/s.
Answer
(A) the average velocity between R and Q is 15 m/s, (B) the ratio of time to go from P to R and that from R to Q is 3: 2, (D) the average velocity between P and R is 10 m/s.
