Abiker is riding with a speed of 15 m/s. a dog runs out in front of the biker, who slams on the brakes and comes to a stop 2 seconds later. what distance did the biker travel before coming to a stop?

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
