Detailed Solution finding Kinetic Energy for m = 619 lb, v = 781 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 = 619 lb & Velocity = 781 mph:
Given that,
mass (m) = 619 lb
velocity (v) = 781 mph
⇒ Convert the mass 619 lb to "Kilograms (kg)"
Mass in Kg = 619 ÷ 2.204623
Mass in kg = 280.7736 kg
=> Convert Distance value 781 mph to "meters (m)"
Distance in meters = 781 x 1609
Distance in meters (m) = 349.1283 m
Substitute the value into the formula
KE = 17111828.5013 J
∴ Kinetic Energy (KE) = 17111828.5013 J
KE for m = 619 lb, v = 781 mph Results in different Units
