Detailed Solution finding Kinetic Energy for m = 785 lb, v = 947 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 = 785 lb & Velocity = 947 mph:
Given that,
mass (m) = 785 lb
velocity (v) = 947 mph
⇒ Convert the mass 785 lb to "Kilograms (kg)"
Mass in Kg = 785 ÷ 2.204623
Mass in kg = 356.0699 kg
=> Convert Distance value 947 mph to "meters (m)"
Distance in meters = 947 x 1609
Distance in meters (m) = 423.3348 m
Substitute the value into the formula
KE = 31906070.2415 J
∴ Kinetic Energy (KE) = 31906070.2415 J
KE for m = 785 lb, v = 947 mph Results in different Units
