Finding Impact of m 21 kg and v = 43 mph

Detailed Procedure to Calculate Impact Force for m = 21 kg, v = 43 mph & d = 5 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 = 21 kg & Velocity = 43 mph & Distance = 5 mm:

Given that,

mass (m) = 21 kg

velocity (v) = 43 mph

distance (d) = 5 mm

⇒ Convert Velocity value 43 mph to " m/s"

Velocity in m/s = 43 ÷ 2.237

Velocity in m/s = 19.2222 m/s

⇒ Convert Distance value 5 mm to " m"

Distance in m = 5 ÷ 1000

Distance in m = 0.005 m

Substitute the value into the formula

F =
21 x (19.2222)2 / 0.005

F = 775933.027042 N

∴ Imapct Force (F) = 775933.027042 N

Impact Force for m = 21 kg, v = 43 mph & d = 5 mm Results in different Units
