Answer:

172.19 km, N 34.18° E

Explanation:

The turn made at the end of the first leg is 90°, so the total displacement can be found using the Pythagorean theorem.

d = √(75^2 +155^2) = √29650

d ≈ 172.19 . . . km

The direction can be found from the angle between the initial leg and the end point. That angle is ...

α = arctan(155/75) ≈ 64.18°

Then the direction from the starting position to the final position is ...

-30° +64.18° = 34.18° . . . . east of north

The total displacement of the airplane is ...

172.19 km, N 34.18° E

Explanation:

DetaM=4 x 1.02875 - 4.002603

DetaM= 0.028697u

Using E= mc²

= 0.028697 x 1.49x*10^-10

= 4.2x10^-12J

a runner covers the last straigjt stretch of a race in 4 s. during that time, he speeds up from 5m/s to 9m/s.

PtichkaEL [24]

During that final period of time,
his acceleration is
(9 m/s - 5 m/s) / (4 sec) = 1 m/s² .
