Detailed Solution finding Kinetic Energy for m = 781 lb, v = 943 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 = 781 lb & Velocity = 943 mph:
Given that,
mass (m) = 781 lb
velocity (v) = 943 mph
⇒ Convert the mass 781 lb to "Kilograms (kg)"
Mass in Kg = 781 ÷ 2.204623
Mass in kg = 354.2556 kg
=> Convert Distance value 943 mph to "meters (m)"
Distance in meters = 943 x 1609
Distance in meters (m) = 421.5467 m
Substitute the value into the formula
KE = 31475897.441 J
∴ Kinetic Energy (KE) = 31475897.441 J
KE for m = 781 lb, v = 943 mph Results in different Units
