An airplane increases its speed from 100 m/s to 160 m/s, at the average rate of 15 m/s2. how much time does it take for the complete increase in speed? 00577s o 40s o 0.25s o 17.3s

4 s

Explanation: In order to solve this problem we have to use tge following kinematic expression:

vf=vo+a*t;  where vf and vo are the final and initial speed. a is the average acceleration and t,the time.

then we have:

t= (160-100) m/s/(15 m/s^2)= 4 s

4.0 s

Explanation:

Given data

Initial speed (V₀): 100 m/s

Final speed (vf): 160 m/s

Acceleration (a): 15 m/s²

Time (t): ?

In an uniformly accelerated motion, the acceleration is equal to the change in the speed divided by the time elapsed.

a = Δv/t

t = Δv/a = (vf - V₀)/a = (160 m/s - 100 m/s)/ (15m/s²) = 4.0 s

are there options? cause you ain’t. real specific
