Finding Impact of m 46 lb and v = 81 mph

Detailed Procedure to Calculate Impact Force for m = 46 lb, v = 81 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 = 46 lb & Velocity = 81 mph & Distance = 100 mm:

Given that,

mass (m) = 46 lb

velocity (v) = 81 mph

distance (d) = 100 mm

⇒ Convert the mass 46 lb to "Kilograms (kg)"

Mass in Kg = 46 ÷ 2.204623

Mass in kg = 20.8652 kg

⇒ Convert Velocity value 81 mph to " m/s"

Velocity in m/s = 81 ÷ 2.237

Velocity in m/s = 36.2092 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 =
20.8652 x (36.2092)2 / 0.1

F = 136782.825819 N

∴ Imapct Force (F) = 136782.825819 N

Impact Force for m = 46 lb, v = 81 mph & d = 100 mm Results in different Units
