B. 0.2 m/s^2 east
C. 1 m/s^2 east
D. 5 m/s^2 east

Respuesta :

Answer;

0.2 m/s²,east

Explanation;

Using the equation;

v = u+at

Where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.

making a the subject;

a= (v-u)/t

  = (19 -18)/5

  = 1/5

  = 0.2 m/s², east
