Detailed Solution finding Kinetic Energy for m = 485 lb, v = 647 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 = 485 lb & Velocity = 647 mph:

Given that,

mass (m) = 485 lb

velocity (v) = 647 mph

Convert the mass 485 lb to "Kilograms (kg)"

Mass in Kg = 485 ÷ 2.204623

Mass in kg = 219.9923 kg

=> Convert Distance value 647 mph to "meters (m)"

Distance in meters = 647 x 1609

Distance in meters (m) = 289.2266 m

Substitute the value into the formula

KE =
1 / 2
x 219.9923 x ( 289.2266 )2

KE = 9201401.9395 J

∴ Kinetic Energy (KE) = 9201401.9395 J
