A car is moving 18 m/s to the eat. If it takes the car 5 seconds to reach a velocity of 19 m/s to the east, what is its acceleration?

A. 0.2 m/s^2 west

B. 0.2 m/s^2 east

C. 1 m/s^2 east

D. 5 m/s^2 east

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
