The verical of point above the ground is twice that of Q. A particle is projected downward with a speed of `5 ms^(-1)` from P and at the same time another particle is projected upward with the same speed from W. Both particle reach the ground simultaneously, then

Height of a tower is 125m and a particle is dropped from rest from the top of the tower. After two seconds of its fall, another particle is projected downwards with a speed u such that both the particles reach the ground simultaneously. What is the value of u?

There is one tower of height h. one particle A is projected upward from top of the tower with a speed u_(1) at time t=0 . At time t= t_(0) another particle B is projected upward from the bottom of the tower with a speed u_(2) . When will the particles cross each other?

Assertion Particle-1 is dropped from a tower and particle-2 is projected horizontal from the same tower. Then both the particles reach the ground simultaneously. Reason Both are particles strike the ground with different speeds.

There is a tower of height 20m and a particle is projected up from top of the tower with an initial speed 20m//s. Top of the tower is marked as point A, from where particle is projected. Point of maximum height a denoted as B. When particle reaches the point A during downward journey then we call the same point as C. Point at the bottom of tower is marked as D where particle finally strikes. Acceleration due to gravity g=10m//s^(2) Time taken by the particle to reach the ground is

A particlele is projected vertically upwards from the ground with a speed V and a speed v and a second particle is projected at the same instant from a height h directly above the first particel with the same speed v at an angle of projection theta with the horizontal in upwards direction. The time when the distance between them is minimum is
