An airplane increases its speed at the average rate of 15 m/s².How much time does it take to increase its speed from 100 m/s to 160 m/s? A)17 s B)0.058 s C)4.0 s D)0.25 s

Question

Quizplus · Accepted Answer

The initial velocity, u = 100 m/s
Final velocity, v = 160 m/s
Acceleration, a = 15 m/s²

We can use the formula:
v = u + at

Rearranging to isolate t, we get:
t = (v-u)/a

Substituting the given values:
t = (160 - 100) / 15
t = 4 seconds

Therefore, the time taken for the airplane to increase its speed from 100 m/s to 160 m/s is 4 seconds. Option C is the correct choice.
