The six hit by CHRIS GAYLE in IPL just misses a building of length 80m as shown in figure. The angle of projection with horizontal is :-

A ball thrown down the incline strikes at a point on the incline 25m below the horizontal as shown in the figure. If the ball rises to a maximum height of 20m above the point of projection, the angle of projection alpha (with horizontal x axis) is

A particles is projected horizontally with a speed v from the top of a plane inclined at an angle tehta to the horizontal as shown in the figure. (a) Hwo far from the point of projection will the particle strike the plane ? (b) Find the time taken by the particel to hit the plane. (c) What is the velocity of particle just before it hits the plane ?

Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

A particle is projected at an angle of 45^(@) with the horizontal with a speed u in a uniform gravitational field, as shown in the figure. The instaneous angular speed of the particle w.r.t. Point of projection at the moment if falls at the same horizontal level equals

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

A particle is projected in air at some angle to the horizontal , moves along parabola shown in the figure where x and y indicate horizontal and verticle diections, respectively. Shown in the diagram, direction of velocity and acceleration at point A,B and C.
