Question

A particle is projected vertically upward with initial velocity 25 m/s . During third second of its motion which of the following statement is correct? A) displacement of particle is 30 m B) distance covered by particle is 30 m. C) Distance covered by particle is 2.5 m D) None of these

Answer 1

The right option for this answer is none of the above because the displacement of the concerned particle would be of maximum magnitude when it is equal to 2.5s while the velocity of the particle would be zero when it starts to turn back.

In this case, the distance would come to 31.35m, which is equal to 3s the additional distance traveled by the concerned particle would be 1.25m in the direction opposing it and therefore the total distance traveled would be equal to thirty-three meters.
