Finding Impact of m 79 lb and v = 120 ft/s

Detailed Procedure to Calculate Impact Force for m = 79 lb, v = 120 ft/s & d = 0.1 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 = 79 lb & Velocity = 120 ft/s & Distance = 0.1 ft:

Given that,

mass (m) = 79 lb

velocity (v) = 120 ft/s

distance (d) = 0.1 ft

⇒ Convert the mass 79 lb to "Kilograms (kg)"

Mass in Kg = 79 ÷ 2.204623

Mass in kg = 35.8338 kg

⇒ Convert Velocity value 120 ft/s to " m/s"

Velocity in m/s = 120 ÷ 3.281

Velocity in m/s = 36.5854 m/s

⇒ Convert Distance value 0.1 ft to " m"

Distance in m = 0.1 ÷ 3.281

Distance in m = 0.0305 m

Substitute the value into the formula

F =
35.8338 x (36.5854)2 / 0.0305

F = 786835.229704 N

∴ Imapct Force (F) = 786835.229704 N

Impact Force for m = 79 lb, v = 120 ft/s & d = 0.1 ft Results in different Units
