JEE Main Physics question
A particle starts from rest and traverses a distance with uniform acceleration, then moves uniformly over a further distance and finally comes to rest after moving a further distance under uniform retardation. Assuming entire motion to be rectilinear motion, the ratio of average speed over the journey to the maximum speed on its way is
Answer: (B)
Solution
Let the max speed be . Phase 1 (rest over ): . Phase 2 (uniform, at ): . Phase 3 ( over
