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?

A particle is projected horizontally will speed 20 ms^(-1) from the top of a tower. After what time velocity of particle will be at 45^(@) angle from initial direction of projection.

Two particles A and B are projected simultaneously from a fixed point of the ground. Particle A is projected on a smooth horizontal surface with speed v, while particle B is projected in air with speed v, while particle B is projected in air with speed (2v)/(sqrt(3)) . If particle B hits the particle A, the angle of projection of B with the vertical is

A particle is projected at an angle theta from ground with speed u (g = 10 m/ s^2 )

A particle is projected at angle theta with horizontal from ground. The slop (m) of the trajectory of the particle varies with time (t) as

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.
