If velocity of flow is 4 m/s, then velocity head is

A particle is moving eastward with a velocity of 5m/s in 10 s the velocity changed by 5m/s northwards.The change in velocity is

A body of mass 2 kg, travelling at 4 m/s makes a head-on collision with a body of mass 1 kg travelling in the opposite direction with a velocity of 2 m/s, the velocities of the two bodies after collision are

Velocity of a swimmer with respect to a river is (hat i+4hat j)m/s and velocity of the river flow is (2hat j)m/s then velocity of swimmer with respect to ground is (in m/s)

The velocity in m/s of a particle is proportional to the cube of the time. If the velocity after 2 s is 4m/s, then v is equal to

Rain is falling vertically downward with velocity 4m//s. A man is moving horizontally with velocity 3 m//s , the velocity of rain with respect to man is

Rain is falling vertically downward with velocity 4m//s. A man is moving horizontally with velocity 3 m//s , the velocity of rain with respect to man is

A particle travels A to M along a straight line with a velocity of 8 m/s and M to A with a velocity of 2 m/s, then the average velocity for the whole journey is –

The velocity of kerosene oil in a horizontal pipe is 5 m/s. if g = 10 m/s^2 , then the velocity head of oil will be
