Physics! - PLEASE HELP

posted by .

A 75 kg passenger in a van is wearing a seat belt whent he van moving at 15m/s, collides with a conrete wall. The front end of the van collapses 0.50 m as it comes to rest.
a) what was the paseenger's kinetic energy before the crash
b) What average force did the seat belt exert on the passengfer during the crash?

  • Physics! - PLEASE HELP -

    KE= 1/2 mv^2
    Force*distance= 1/2 mv^2 solve for force
