Question

What is the force acting on a seat with a 180 lbs person if the car is rear ended from another car at 50 miles an hour differance. Make any assumptions you need.

Answer 1

3.667 lbf

Step-by-step explanation:

m=180 lbs given

acceleration of the car as the car is rear ended with other car

a=
`(50-0)/(1)`=50 miles/
`hr^2`

=50miles/
`hr^2`

=
`(5* 5820)/(3600^2)` ft/
`sec^2`

=0.02037 ft/
`sec^2`

now force acting on the seat= ma

where m=mass

a= acceleration

f=180×0.02037

=3.667 lbf
