A ball thrown by a boy is caught by another after 2 sec . some distance away in the same level. If the angle of projection is `30^(@)`, the velocity of projection is

A gun fires at an angle 30^@ with the horizontal and hits a target at a distance of 3 km . Can another target at a distance of 5km be hit by changing the angle of projection but keeping the velocity of projection unchanged ?

A ball is projected from ground in such a way that after 10 seconds of projection it lands on ground 500 m away from the point of projection. Find out :- (i) angle of projection (ii) velocity of projection (iii) Velocity of ball after 5 seconds

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection is

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection is

A ball is projected horizontally. After 3s from projection its velocity becomes 1.25 times of the velocity of projection. Its velocity of projection is

Two balls A and B are thrown with speeds u and u//2 , respectively. Both the balls cover the same horizontal distance before returning to the plane of projection. If the angle of projection of ball B is 15^@ with the horizontal, then the angle of projection of A is.
