Detailed Solution finding Kinetic Energy for m = 812 lb, v = 974 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 = 812 lb & Velocity = 974 mph:

Given that,

mass (m) = 812 lb

velocity (v) = 974 mph

Convert the mass 812 lb to "Kilograms (kg)"

Mass in Kg = 812 ÷ 2.204623

Mass in kg = 368.3169 kg

=> Convert Distance value 974 mph to "meters (m)"

Distance in meters = 974 x 1609

Distance in meters (m) = 435.4046 m

Substitute the value into the formula

KE =
1 / 2
x 368.3169 x ( 435.4046 )2

KE = 34912234.436 J

∴ Kinetic Energy (KE) = 34912234.436 J
