A bird moves from point `(1, -2, 3)` to `(4, 2, 3)`. If the speed of the bird id `10 m//s`, then the velocity of the bird is :-

A bird moves from point (1 m, -2 m, 3 m) to (4 m, 2 m, 3 m) . If the speed of the bird is 10 m//s , then the velocity vector of the bird in m//s is:

A bird moves from point (1 m, -2 m, 3 m) to (4 m, 2 m, 3 m) . If the speed of the bird is 10 m//s , then the velocity vector of the bird in m//s is:

A bird moves from point (1 m, -2 m, 3 m) to (4 m, 2 m, 3 m) . If the speed of the bird is 10 m//s , then the velocity vector of the bird in m//s is:

A bird flies to and fro between two cars which moves with velocities v_1 = 20 m//s and v_2 = 30 m//s . If the speed of the bird is v_3 = 10 m//s and the initial distance of separation between them is d = 2 km , find the total distance covered by the bird till the cars meet.

A bird flies from (-3m, 4m, -3 m) to (7m, -2m, -3m) in the xyz-coordinates. The bird's displacement vector is given by

A bird flies from (-3m, 4m, -3 m) to (7m, -2m, -3m) in the xyz-coordinates. The bird's displacement vector is given by

A bird is sitting on the top of a vertical pole 20 m high and its elevation from a point O on the ground is 45o . It flies off horizontally straight away from the point O. After one second, the elevation of the bird from O is reduced to 30o . Then the speed (in m/s) of the bird is (1) 40(sqrt(2)-1) (2) 40(sqrt(3)-2) (3) 20""sqrt(2) (4) 20(sqrt(3)-1)
