AB is a firictionless inclined surface making an angle of 30° with horizontal. A is 20 m above the ground while B is 10 m above the ground. A block slides down from A, initially starting from rest. Its velocity on reaching B is

A body is thrown with a velocity of 9.8 m/s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A body is thrown with a velocity of 9.8 m//s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A body is thrown with a velocity of 9.8 m//s making an angle of 30^(@) with the horizontal. It will hit the ground after a time

A particle is projected from ground with some initial velocity making an angle of 45^(@) with the horizontal. It reaches a height of 7.5 m above the ground while it travels a horizontal distance of 10 m from the point of projection. The initial speed of the projection is

If the ladder is inclined at an angle of 30^(@) with the ground and it reaches at a height of 4m from the ground, the the length of the ladder is

A particle is projected from the ground with some initial velocity making an angle of 45^(@) with the horizontal. It reaches a height of 7.5 m above the ground while it travels a horzontal distance of 10 m from the point of projection . Find the initial speed of projection ( g = 10 m//s^(2) ) .

Walking 20m on a slope of inclination 30^(@) with the level ground, one reaches 10m above the ground level.
