From a tower of height H, a particle is thrown vertically upwards with a speed u. The time taken by the particle, to hit the ground, is n times that taken by it to reach the highest point of its path. The relation between H, u and n is

From a tower of height H , a particle is thrown vertically upwards with a speed u . The time taken by the particle , to hit the ground , is n times that taken by it to reach the highest point of its path. The relative between H, u and n is :

A ball is thrown upwards with a speed u from a height h above the ground.The time taken by the ball to hit the ground is

A ball is thrown vertically upward with a velocity u from the top of a tower. If it strikes the ground with velocity 3u, the time taken by the ball to reach the ground is

A stone is thrown vertically upwards with a velocity of 4.9 ms^(-1) . Calculate : the time taken to reach the ground.

A stone is thrown vertically upwards with an initial speed u from the top of a tower, reaches the ground with a speed 3 u . The height of the tower is :

A projectile is thrown at angle beta with vertical.It reaches a maximum height H .The time taken to reach the hightest point of its path is

Assertion : A body is dropped from height h and another body is thrown vertically upwards with a speed sqrt(gh). They meet at height h/ 2. Reason : The time taken by both the blocks in reaching the height h/2 is same.

A particle is projected vertically upwards from ground with velocity 10 m // s. Find the time taken by it to reach at the highest point ?

A ball is thrown straight upward with a speed v from a point h meter above the ground. The time taken for the ball to strike the ground is
