Finding Impact of m 278 lb and v = 138 mph

Detailed Procedure to Calculate Impact Force for m = 278 lb, v = 138 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 = 278 lb & Velocity = 138 mph & Distance = 30 ft:

Given that,

mass (m) = 278 lb

velocity (v) = 138 mph

distance (d) = 30 ft

⇒ Convert the mass 278 lb to "Kilograms (kg)"

Mass in Kg = 278 ÷ 2.204623

Mass in kg = 126.0987 kg

⇒ Convert Velocity value 138 mph to " m/s"

Velocity in m/s = 138 ÷ 2.237

Velocity in m/s = 61.6898 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 =
126.0987 x (61.6898)2 / 9.1436

F = 26241.680686 N

∴ Imapct Force (F) = 26241.680686 N

Impact Force for m = 278 lb, v = 138 mph & d = 30 ft Results in different Units
