Science - A mass of 55kg is riding in a car at 20m. The car slams on the brakes. The seatbelts stop?

Question

...  the mass from flying forward bringing it to rest in 0.5 seconds. How much force did the seatbelts put on the mass?

Answer

"20m" is meaningless in this context. You can not stand mistrakes.

I assume you meant 20 mps. So you decelerate 20 mps in 0.5 s. That equals 40m/s^2. Now f = ma = 55 kg x 40 m/s^2 = 220 newtons.
