What was the average force exerted on your carduring braking

Reference no: EM13646816

Driving home from school, you spot a ball rolling out into the street. You brake for 1.20 s, slowing your 950 kg car from 16.0 m/sto 9.50 m/s.

a) What was the average force exerted on your carduring braking?
b) How far did you travel while braking?
