How do you calculate mass when given joules and velocity?
Kinetic energy = (1/2) (mass) (velocity squared)Divide each sideby (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared
How is the radius of rotation related to the centripetal force and angular velocity?
Assuming that angles are measured in radians, and angular velocity in radians per second (this simplifies formulae): Radius of rotation is unrelated to angular velocity. Linear velocity = angular velocity x radius Centripetal acceleration = velocity squared / radius Centripetal acceleration = (angular velocity) squared x radius Centripetal force = mass x acceleration = mass x (angular velocity) squared x radius
How do you calculate the initial speed?
v2 = u2+ 2as where v squares is the final velocity , u squared is the initial velocity , a is the acceleration and s is the distance travelled. If it is free fall take a = 10m/s squared ( as gravity ).
What is the velocity of a square?
Please reword this question, since in its present form, it doesn't make sense. Right now, it sounds like a square is flying through the air. Maybe you are asking about velocity squared? If so, velocity means both the speed and direction of something. For velocity squared, it would essentially be just multiplying the speed by itself.
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
How do you find displacement when you only have acceleration initial velocity and final velocity?
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
What are units for velocity squared?
The SI unit for velocity is m/s. Therefore the SI units for velocity squared would be m2/s2.

What is the homogeneity of v2 equals u2 plus 2as?
Each term in the equation has dimensions of velocity-squared (remember "a" here is acceleration which is velocity divided by time, so "as" is velocity x distance / time = velocity squared).
What is the velocity if travel 5.7 meters per second squared for 4 seconds?
Velocity can be measured in metres per second, not metres per second squared. Acceleration is measured in metres per second squared but knowing only the acceleration does not help in finding the velocity.

Why the second is squared in acceleration?
it is very simple........... velocity or speed = distance / time. acceleration = velocity / time but, we know that velocity = distance / time so just substitute the equation of velocity in acceleration...... so, finally we get , acceleration = distance/time*time so it is time squared.
How do you square velocity?
While you cannot physically square your velocity, such as you are traveling at 10 meters per second, and then there's another dimension where you are 100 meters squared per second squared, velocity squared comes up in various physics calculations. Kinetic energy of an object in motion is (1/2)*mass*(velocity squared). This just means that you take the velocity and square the number, and also square the units, so (10 m/s)2 = 100 m2 / s2 for the calculation.
5.7 meters per second squared for 4 seconds what is velocity?
It is not possible to answer this question without the starting velocity.
State in words how acceleration is calculated?
There are two methods, it depends on what variables you have: 1. Subtract the initial velocity from the final velocity and divide that whole term by the time (Vf- Vi)/t = a 2. Square both the initial velocity and the final velocity and subtract the squared inital velocity from the squared final velocity and that answer by two times the distance (Vf^2 - Vi^2)/2d = a
Volume flow rate formula?
pi*radius squared*velocity
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)
