A ball is projected in a manner such that its horizontal gange is n times of the maximum height. Then find out the ratio of potential energy to kinetic energy at maximum height.

A stone is projected vertically up to reach maximum height h. The ratio of its potential energy to its kinetic energy at a height 4/5h , will be

For which angle of projection the horizontal range is 5 times the maximum height attrained ?

The horizontal range is four times the maximum height attained by a projectile . The angle of projection is

The horizontal range is four times the maximum height attained by a projectile. The angle of projection is

A body is projected at an angle of 60^(@) with horizontal. If its kinetic energy at its maximum height is 10 J, then the height at which its potential energy and kinetic energy have equal values is (consider potential energy at the point of projection to be zero)

A body is projected at an angle of 60^(@) with horizontal. If its kinetic energy at its maximum height is 10 J, then the height at which its potential energy and kinetic energy have equal values is (consider potential energy at the point of projection to be zero)

An force 10 N, then its kinetic energy would be zero at maximum height.
