Detailed Solution finding Kinetic Energy for m = 478 lb, v = 640 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 = 478 lb & Velocity = 640 mph:

Given that,

mass (m) = 478 lb

velocity (v) = 640 mph

Convert the mass 478 lb to "Kilograms (kg)"

Mass in Kg = 478 ÷ 2.204623

Mass in kg = 216.8171 kg

=> Convert Distance value 640 mph to "meters (m)"

Distance in meters = 640 x 1609

Distance in meters (m) = 286.0975 m

Substitute the value into the formula

KE =
1 / 2
x 216.8171 x ( 286.0975 )2

KE = 8873430.3916 J

∴ Kinetic Energy (KE) = 8873430.3916 J
