Detailed Solution finding Kinetic Energy for m = 777 lb, v = 939 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 = 777 lb & Velocity = 939 mph:

Given that,

mass (m) = 777 lb

velocity (v) = 939 mph

Convert the mass 777 lb to "Kilograms (kg)"

Mass in Kg = 777 ÷ 2.204623

Mass in kg = 352.4412 kg

=> Convert Distance value 939 mph to "meters (m)"

Distance in meters = 939 x 1609

Distance in meters (m) = 419.7586 m

Substitute the value into the formula

KE =
1 / 2
x 352.4412 x ( 419.7586 )2

KE = 31049592.5534 J

∴ Kinetic Energy (KE) = 31049592.5534 J

KE for m = 777 lb, v = 939 mph Results in different Units
