Detailed Solution finding Kinetic Energy for m = 458 lb, v = 620 mph

Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.

The formula to calculate Kinetic energy is:

KE =
1 / 2
mv2

Where,

KE = Kinetic Energy

m = Mass of object

v = velocity


Step by Step Solution to find Kinetic Energy of Mass = 458 lb & Velocity = 620 mph:

Given that,

mass (m) = 458 lb

velocity (v) = 620 mph

Convert the mass 458 lb to "Kilograms (kg)"

Mass in Kg = 458 ÷ 2.204623

Mass in kg = 207.7453 kg

=> Convert Distance value 620 mph to "meters (m)"

Distance in meters = 620 x 1609

Distance in meters (m) = 277.1569 m

Substitute the value into the formula

KE =
1 / 2
x 207.7453 x ( 277.1569 )2

KE = 7979075.2192 J

∴ Kinetic Energy (KE) = 7979075.2192 J
