Question

a toy airplane is flying at a speed of 8 m/s with an acceleration of 0.9 m/s^2. How fast is it flying after 2 seconds?

Answer 1

9.8m/s this answer is correct.

The acceleration is increasing by 0.9m/s^2.

so, in each second it will increase by 0.9m/s^2.

Therefore, in 2 second

0.9 * 2

= 1.8m/s

Now,

8 + 1.8

= 9.8m/s
