Detailed Solution finding Kinetic Energy for m = 479 lb, v = 641 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:
Where,
KE = Kinetic Energy
m = Mass of object
v = velocity
Step by Step Solution to find Kinetic Energy of Mass = 479 lb & Velocity = 641 mph:
Given that,
mass (m) = 479 lb
velocity (v) = 641 mph
⇒ Convert the mass 479 lb to "Kilograms (kg)"
Mass in Kg = 479 ÷ 2.204623
Mass in kg = 217.2707 kg
=> Convert Distance value 641 mph to "meters (m)"
Distance in meters = 641 x 1609
Distance in meters (m) = 286.5445 m
Substitute the value into the formula
KE = 8919803.2439 J
∴ Kinetic Energy (KE) = 8919803.2439 J
KE for m = 479 lb, v = 641 mph Results in different Units
