Particle projected from tower fo heigh 10m as shown in figure. Find the time (in sec) after which particle will hit the ground.

In the figures shown, three particles are thrown from a tower of height 40 m as shown in figure. In each case find the time when the particles strike the ground and the distance of this point from foot of the tower. , , .

A particle is projected at an angle 60^(@) with speed 10sqrt3 m/s from the point A as shown in the figure. At the same time the wedge is made to move with speed 10sqrt3 m/s toward right as shown in figure. Find the time after which particle will strike the wedge.

A particle is projected from a tower as shown in figure, then find the distance from the foot of the tower where it will strike the ground. (g=10m//s^(2))

A particle is projected from a tower as shown in figure, then find the distance from the foot of the tower where it will strike the ground. (g=10m//s^(2))

A particle is projected from a tower as shown in figure, then find the distance from the foot of the tower where it will strike the ground. (g=10m//s^(2))

Five particles are projected simultaneously from the top of a tower that is h = 32 m high. The initial velocities of projection are as shown in figure. Velocity of 2 and 5 are horizontal. (a) Which particle will hit the ground first? (b) Separation between which two particles is maximum at the instant the first particle hits the ground? (c) Which two particles are last and last but one to hit the ground? Calculate the distance between these two particles (still in air), at a time 0.3s after the third particle lands on ground. [g = 10 m//s^(2), tan 37^(@) = (3)/(4)]
