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, -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, -2) to (4, 2) . If the speed of the bird is 10m//sec , then find the velocity vector of the bird ?

A bird flies from (-3 m,4 m,-3 m ) to (7 m, -2 m, -3 m) in XYZ co-ordinates. The bird's displacement in unit vectors 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 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.

Five particles have speeds 1, 2, 3, 4, 5 m/s. The average velocity of the particles is (in m/s)

A particle moves in xy-plane from position (1m,2m) to (3m,4m) in 2s. Find the magnitude and direction of average velocity.

An object is displaced from point A(2m,3m,4m,) to a point B (1m,2m,3m)N. Find the work done by this force in this process.

An object moves the first half of the total distance with a speed of 2 m s^(-1) . If the average of the body is 3m s ^(-1) , the speed of the body when it travelles the remaining distance is _______ m s^(-1)
