A particle is projected with speed of u at an angle `theta` to the horizontal on an inclined surface making an angle `ϕ (ϕ<θ)` to the horizontal. Find an expression for its along the inclined surface.

A projectile is projected with velocity u making an angle theta with the horizontal, the equation of the path of the projectile is given by

A particle is projected with velocity 2sqrt(gh) and at an angle 60^@ to the horizontal so that it just clears two walls of equal height 'h' which are at a distance 2h from each other. The time taken by the particle to travel between these two walls

A stone is projected with velocity of 100 m/s at an angle of 60^@ with the horizontal, its maximum height is

Two stones are projected with the same speed but making different angles with the horizontal. Their ranges are equal. If the angle of projection of one is (pi^c)/3 and its maximum height is H, then the maximum height of the other is

A particle is projected with a velocity v so that its horizontal range twice the greatest height attained. The horizontal range is

A particle of mass m is projected from the ground with an initial speed u_0 at an angle alpha with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed u_0. The angle that the composite system makes with the horizontal immediately after the collision is

At what angle will the horizontal range be maximum?

A projectile thrown with a speed v at an angle theta has a range R on the surface of earth. For same v and theta , its range on the surface of moon will be

A block of mass m is lying on horizontal surface of coefficient of friction mu. A force is applied to the block at an angle theta with the horizontal. The block will move with a minimum force F if

A body is projected with a vertical velocity of 30 m//s at an angle of 30^@ with the horizontal, the maximum height and horizontal range are respectively
