[" II "u=ai+bj+ck" With "i,j,k," are the east,north and vertical directions,the maximum height "],[" of the projectile is "]

If vecu=ahati+bhatj+chatk with hati,hatj,hatk are in east, north and vertical directions, the maximum height of the projectileis

If vecu=ahati+bhatj+chatk with hati,hatj,hatk are in east, north and vertical directions, horizontal component of velocity of projectile is

A body projected from the top of a tower with a velocity u = 3i + 4j + 5k ms^(-1) . Where hatj and hatk are unit vectors along east, north and vertically upwards respectively. If the height of the tower is 30 m, horizontal range of the body on the ground is(g = 10ms^(-2) )

An object is projected with speed u and range of the projectile is found to be double of the maximum height attained by it . Range of the projectile is .

An object is projected with speed u and range of the projectile is found to be double of the maximum height attained by it . Range of the projectile is .

If a projectile is fired at an angle theta with the vertical with velocity u, then maximum height attained is given by:-

If a projectile is fired at an angle theta with the vertical with velocity u, then maximum height attained is given by:-

If a projectile is fired at an angle theta with the vertical with velocity u, then maximum height attained is given by:-

An object is thrown in vertical upward direction with velocity 'u' then the maximum height attained by the object would be....
