Keeping the angle of' projection same, what is'the effect on horizontal range of a particle when its velocity is doubled?

Find the angle of projection so that a body when projected has the horizontal range equal to the maximum height attained.

What is the angle of projection at which the h_(max and Range are equal?

Find the path of projectile, time of flight, horizontal range and maximum height, when a projectile is projectile is priojected with velocity v making an angle Theta with the vertical direction.

What are the possible angles of projection with the same velocity to have same range?

The kinetic energy of an object of mass, m moving with a elocity of 5 ms^-1 , is 25J. What will be its kinetic energy when its velocity is doubled? What will be its kinetic energy when its velocity is increased three times?

What will be the potential energy of a body when its mass becomes doubled.

The height and horizontal distance of a projectile are y= 8t-5t^2 m and x=6t m. its projection velocity is

A bullet fired at an angle of 30^@ with the horizontal hits the ground 3.0 km away. By adjusting its angle of projection, can one hope to hit a target 5.0 km away? Assume the muzzle speed to the fixed, and neglect air resistance.

A body is projected with a speed v at an angle theta with horizontal to have maximum range. What is the velocity at the highest’ point?
