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 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 ).
How do you get the displacement if the if the final velocity is not given?
Use s=ut+0.5at^2 (^2 notation for squared)Or calculate the final velocity from the known variables (Initial Velocity, Acceleration and Time)v=u+at Where V = Final Velocity, u = Initial Velocity, a = Acceleration, t = TimeThen calculate displacement (s) using s=0.5(u+v)t
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
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term

How cn you calculate kinetic energy?
Kinetic Energy = 1/2 Mass * Velocity squared

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.
How do you calculate impact energy of a flying object?
Kinetic Energy= 1/2 m vv ( v squared,I don't know how to do exponentials on my computer). or one half mass times velocity squared.
How do you calculate tota distance traveled when given velocity time and acceleration?
Assuming constant acceleration: distance = v(0) t + (1/2) a t squared Where v(0) is the initial velocity.
How do I calculate acceleration from change in velocity and distance?
change in velocity (v) = acceleration (a) x time (t); distance s = 1/2 a times t squared; solve for time and substitute; find a = v squared /(2s)
Calculate the kinetic energy of a K mass that is moving with a velocity of 2.0 ms?
Use the formula:KE = (1/2) x mass x speed squared
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).
The formula half the mass times the velocity squared is used to calculate what type of energy?
that is kinetic energy
