A particle is projected at an angle of 45° with a velocity of 9.8 metre per second. The horizontal range will be

Two balls are projected respectively from the same point in directions inclined at 60D and 30° to the horizontal. If they attain the same height, the ratio of their velocities of projection is

f a projectile having horizontal range of 24 acquires a maximum height of 8, then its initial velocity and the angle of projection are

The range of a projectile fixed at an angle of 15° is 50 m, if it is fixed with the same speed at an angle of 45^o, then the range will be

A particle is projected from a point 0 with velocityu at an angle of 60^o with the horizontal. When it is moving in a direction at right angles to its direction at 0, its velocity then is given by

AB is the vertical diameter of a circle in a vertical plane. Another diameter CD makes an angle of 60° with AB, then the ratio of the time taken by a particle to slide along AB to the time taken by it to slide along CD is

A particle is projected up a smooth inclined plane of inclination 60° along the line of greatest slope. If it comes to instantaneous rest after 2 second then the velocity of projection is (g = 9.8 m/sec²)

A body is projected through an angle a from vertical so that its range is half of maximum range, a is

The velocity and direction of projection of a shot which passes in horizontal direction just over the top of a wall which is 50 yds. away and 75 feet high

If the time taken in slipping down on smooth inclined plane is twice to the time taken in falling from the vertical height of that plane, then the inclination of plane will be
