Calculating velocity of a particle if distances are constant In that case, A and B are satellites of C, and when the three particles become collinear (distance between A and B is 10 m), A stops moving "towards B with velocity 5 m s and B" stops moving "towards A with same speed as A" Indeed The equations will lead to the y coordinate (distance from C to the line AB) becoming imaginary
Calculating Nozzle Flow Rate - Physics Forums Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
Finding Velocity given x and y velocities - Physics Forums 1 How do you find the velocity of an object if you are given the x and y components of the velocity? 2 Not sure! 3 It makes the most sense to use the Pythagorean Theorem to find the magnitude then trig to find the angle, but I've got a classmate telling me you simply add
Is Velocity Increasing Below the X-Axis? - Physics Forums Here, the signs of the one dimensional velocity and acceleration vectors can be used to summarize, rather compactly, what is "actually" happening according to the graph The rule is simple: If the product of the velocity and the acceleration is a positive number, the speed is increasing; if it is a negative number the speed is decreasing
Permeability of Metglas and Propagation Velocity The first is the velocity of wave propagation along the boundary between the material and air or space That will be close to the speed of light, slowed down by the dielectric constant of the surface coating The second is the velocity of propagation into the material, perpendicular to the surface, which is much slower
Understanding Angular Velocity: W = 2pi (f) - Physics Forums Can anyone explain to me how angular velocity (w) = 2pi(f) -->where f = frequency This is not a homework question involving numbers I'm reading a section on "the period of sinusoidal Nature of SHM" and I don't understand how they get this equation
Can force be expressed as mass flow rate times velocity Newton's law is actually that force is the rate of change of momentum with time, Therefore, So, if you have a constant velocity, then yes, force can be simply the rate of change of mass times velocity
What Are Ordinary and Proper Velocities in Special Relativity? The third convention, like the second convention, borrows from the first convention (proper time, proper energy, etc ), but it uses "proper velocity" and "proper force" as synonyms for the velocity and force four-vectors
Solving F=MA: Boat Acceleration, Distance, Velocity (C) what will the velocity be in the end of that time? (D) what is the boat weight? Homework Equations The Attempt at a Solution I know that the netforce will be 18000N but I really don't know where to go from there I know the F=ma but without extra information I don't know what to do Please help Where did you get this problem?
