3. Sarah, who has a mass of 55 kg, is riding in a car at 20 m/s. She sees a cat crossing the street and slams on the brakes! Her seatbelt stops her from flying forward, bringing her to rest in 0.5 seconds. How much force did the seatbelt put on Sarah?

Respuesta :

force = (kg)(m/s^2) 


If we plug in the values, force = (55kg)((20m/s)/0.5s) = (55g)(40m/s^2) = 2200N

Answer:

Force = (kg)(m/s^2)  

Explanation:

If we plug in the values, force = (55kg)((20m/s)/0.5s) = (55g)(40m/s^2) = 2200N
