Finding velocity from kinetic energy
Webv = final velocity, u = initial velocity, a = acceleration, and Δs denotes change in displacement ΔK = maΔs, so from equation (1) ΔK = m (v^2 - u^2) / 2 => ½ mv^2 - ½ mu^2 but If kinetic energy is the energy of motion then, naturally, the kinetic energy of an … V= instantaneous velocity; Since acceleration and velocity are in the …

WebTo calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules. Example 2: A ball which weighs 500 grams has a kinetic energy of 500 J. WebThe two equations that describe the potential energy (PE) and kinetic energy (KE) of an object are: PE = mgh. KE = ½ mv². where m is the mass of the object, g is the height of the object, g is the gravitational field …
WebThis is calculated from taking the initial x position to the final x position (final x - initial x). In this case for the spring, the initial position is the uncompressed mark and the final position is the compressed stage, so delta x would measure how much the spring moved (which in this case more displacement = more compression). 3 comments
