Question

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 1

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
