Detailed Procedure to Calculate Impact Force for m = 81 lb, v = 116 mph & d = 100 mm

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 = 81 lb & Velocity = 116 mph & Distance = 100 mm:

Given that,

mass (m) = 81 lb

velocity (v) = 116 mph

distance (d) = 100 mm

Convert the mass 81 lb to "Kilograms (kg)"

Mass in Kg = 81 ÷ 2.204623

Mass in kg = 36.741 kg

Convert Velocity value 116 mph to " m/s"

Velocity in m/s = 116 ÷ 2.237

Velocity in m/s = 51.8552 m/s

Convert Distance value 100 mm to " m"

Distance in m = 100 ÷ 1000

Distance in m = 0.1 m

Substitute the value into the formula

F =
36.741 x (51.8552)2 / 0.1

F = 493974.692489 N

∴ Imapct Force (F) = 493974.692489 N
