A car starts from rest and travels for 4.3 s with a uniform acceleration of +1.4 m/s2. The driver then applies the brakes, causing a uniform acceleration of -1.8 m/s2. The breaks are applied for 1.80 s.

(a) How fast is the car going at the end of the braking period?

2.78 m/s

(b) How far has the car gone from its start?

m

I have no idea what b is
