Momentum = mass * velocity.
We are told that his momentum is 80kgm/s, and that his mass is 80 kg, so we can say:
80kgm/s = 80 kg × V
∴ 1m/s= V
So the velocity of the man is 1 meter per second west.
Just divide the distance by the time. The answer is in meters/second. If you want to convert that to the more commonly used kilometers/hour, multiply the number of meters/second by 3.6.
Walking in circles ended in 2011.
It all depends at how fast you are walking. a brisk walk is 4.5mph. Therefore it would take about 29.37hours. But like i said, depends how fast you are walking...!
They will be walking 3.72 mph
A 13.42-minute mile equates to a walking speed of 4.47 mph
yes , look at a moving car or a walking person
The energy involved is what causes harm; and that depends on the relative velocity.
Momentum in classical mechanics is defined as mass times velocity. The magnitude of the momentum of an object with mass 3000kg and speed 0.2 m/s has a momentum of 600 mkg/s. A human walking at the same speed of 0.2 m/s weighing, let's say, 100 kg has a momentum of 20 mkg/s which is 30 times smaller.
The elephant
this question has the theoritical answer but it is not yet practically done. according to the theortical answer """"""""yes! elephant have the same momentum as a golf ball<<<<<<<<< Actually, elephants can have the same momentum as a golf ball. the equation for momentum is m x v2. m is mass, v is speed, and the two represents "speed squared". If the golf ball has a huge speed, then yes, it can have the same momentum as the elephant.

Velocity is a measure of the speed of an object that is moving in a specific direction.Imagine walking across the room. If you walk in the same direction and do not change speed, your velocity remains constant until you stop moving. If you keep a constant speed, but change direction while walking, your velocity changes. If you walk in the same direction but slow down and speed up while walking, your velocity changes. Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.In common language, velocity is often used imprecisely to mean "speed".
The law of conservation of momentum is Newton's 3rd law' The vectors sum to zero: 0 = F1 + F2 = dp1/dt + dp2/dt = d(p1 + p2)/dt =0. Thus, p1 + p2 = a constant, thus, the conservation of momentum.

Basically velocity is speed in a specific direction. So just the speed of the person when waking in the wind with a specific direction.
It's a chance in velocity ... and velocity is a vector, NOT a scalar. If in doubt, just make a sharp angled turn while walking (especially on an icy sidewalk).
The elephant would have more momentum because of it has a greater mass and is going faster. The direction really doesn't matter
