Detailed Procedure to Calculate Impact Force for m = 391 lb, v = 251 mph & d = 30 ft

The formula for impact force expressed in terms of the body's velocity (speed) on impact (v), its mass (m), and the collision distance (d) is the formula below:

F =
m x v2 / d

Where,

F = Impact Force

m = Mass of object

v = velocity

d = collision distance


Step by Step Solution to find impact force of Mass = 391 lb & Velocity = 251 mph & Distance = 30 ft:

Given that,

mass (m) = 391 lb

velocity (v) = 251 mph

distance (d) = 30 ft

Convert the mass 391 lb to "Kilograms (kg)"

Mass in Kg = 391 ÷ 2.204623

Mass in kg = 177.3546 kg

Convert Velocity value 251 mph to " m/s"

Velocity in m/s = 251 ÷ 2.237

Velocity in m/s = 112.2038 m/s

Convert Distance value 30 ft to " m"

Distance in m = 30 ÷ 3.281

Distance in m = 9.1436 m

Substitute the value into the formula

F =
177.3546 x (112.2038)2 / 9.1436

F = 122099.216812 N

∴ Imapct Force (F) = 122099.216812 N
