Mathematically, acceleration is given by a=\frac{v-v_{o}}{t} where,
[tex]v \ \rightarrow \text{final-velocity} \\ v_{o} \rightarrow \text{initial-velocity} \\ t \ \rightarrow \text{time}[/tex].
Substituting your values a=-\frac{(60)(10)}{(36)(10)}=-1.666 \ \text{m/s}.

initial velocity, u = 60 km/h = 60 \times \frac{5}{18} =16.67 m/s
final velocity. v = 0
time, t = 10s

acceleration, a =  \frac{v-u}{t}= \frac{0-16.67}{10}=-1.667\ m/s^2

So accelaration is -1.667 m/s²
