Detailed Solution finding Kinetic Energy for m = 649 lb, v = 811 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 = 649 lb & Velocity = 811 mph:

Given that,

mass (m) = 649 lb

velocity (v) = 811 mph

Convert the mass 649 lb to "Kilograms (kg)"

Mass in Kg = 649 ÷ 2.204623

Mass in kg = 294.3814 kg

=> Convert Distance value 811 mph to "meters (m)"

Distance in meters = 811 x 1609

Distance in meters (m) = 362.5391 m

Substitute the value into the formula

KE =
1 / 2
x 294.3814 x ( 362.5391 )2

KE = 19345952.0686 J

∴ Kinetic Energy (KE) = 19345952.0686 J

KE for m = 649 lb, v = 811 mph Results in different Units
