''Acceleration''

Q1.What is similar about the two vehicles is both have a ''Constant Velocity'' of 30mph. And in the same direction, like going north to the same stop. One difference is the ''Speed'' of their ''Acceleration'' the sports car has a more ''Positive Acceleration'' than the school bus because of how it was created for example the school bus was not to look cool and tear up the streets it is to pick up passengers for work or school.Another example would be the bus and sports car size it looks like the bus is really heavy making itself have a ''Negative Acceleration'' in ''Speed'' with the sports car.

Q2. One similarity is the school bus and the sports car is they both have the same speed if the brakes were hit not at the same time for example the sport's car brake were hit 2.5 s earlier than the bus.Another reason is as the  sport's car stop first , the bus will reach the sports car's distance, for example in a 20 m road the sports car stops at 15m at the stoplight the bus will catch up a little later in 5s . One difference is the sport's car will get there first because of the difference in ''Speed'' the two share for example the sports car traveled 5m faster. Another reason is if a person was driving in each one and hit the brake at the same time it is likely that the bus will stop first because its balanced, and the sports car will take little more time to stop like 3s late for example.
