Detailed Solution finding Kinetic Energy for m = 757 lb, v = 919 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 = 757 lb & Velocity = 919 mph:

Given that,

mass (m) = 757 lb

velocity (v) = 919 mph

Convert the mass 757 lb to "Kilograms (kg)"

Mass in Kg = 757 ÷ 2.204623

Mass in kg = 343.3694 kg

=> Convert Distance value 919 mph to "meters (m)"

Distance in meters = 919 x 1609

Distance in meters (m) = 410.8181 m

Substitute the value into the formula

KE =
1 / 2
x 343.3694 x ( 410.8181 )2

KE = 28975477.6904 J

∴ Kinetic Energy (KE) = 28975477.6904 J

KE for m = 757 lb, v = 919 mph Results in different Units
