Detailed Solution finding Kinetic Energy for m = 687 lb, v = 849 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 = 687 lb & Velocity = 849 mph:

Given that,

mass (m) = 687 lb

velocity (v) = 849 mph

Convert the mass 687 lb to "Kilograms (kg)"

Mass in Kg = 687 ÷ 2.204623

Mass in kg = 311.6179 kg

=> Convert Distance value 849 mph to "meters (m)"

Distance in meters = 849 x 1609

Distance in meters (m) = 379.5262 m

Substitute the value into the formula

KE =
1 / 2
x 311.6179 x ( 379.5262 )2

KE = 22442736.9813 J

∴ Kinetic Energy (KE) = 22442736.9813 J

KE for m = 687 lb, v = 849 mph Results in different Units
