Homework Statement
What is the velocity of a 90kg astronaut traveling in outer space with constant velocity?
Homework Equations
W=mass*acceleration
yosty is correct, it's a requirement that he shows all work he's done so far to solve the problem himself, without that, we have no idea where he has run into a problem that we can help him with. Until he completes the template we cannot help him.SteamKing said:Depends on where he's at.
Velocity is a measure of how fast an object is moving in a particular direction. It is a vector quantity, meaning it has both magnitude (speed) and direction.
Velocity is calculated by dividing the displacement of an object by the time it takes to travel that distance. It can also be calculated by multiplying an object's speed by its direction.
An astronaut's mass does not affect their velocity in outer space. According to Newton's Second Law of Motion, an object's mass has no effect on its velocity unless acted upon by an external force.
Velocity and speed are often used interchangeably, but they have different definitions. Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving.
An astronaut's velocity in outer space will remain constant unless acted upon by an external force, such as gravity or a thruster. In the absence of these forces, the astronaut will continue to move at a constant speed and direction.
