The combined speed of the plane and the wind is 249.35 km/h.
<h3>
Relative speed</h3>
The relative speed of the plane due to speed of the wind is calculated as follows;
Let the direction of the plane be horizontal direction.
<h3>Speed of the wind</h3>
The speed of the wind is calculated as follows;

<h3>Combined speed</h3>
The combined speed of the plane and the wind is calculated as follows;
V = 275 km/h - 25.65 km/h
V = 249.35 km/h
Thus, the combined speed of the plane and the wind is 249.35 km/h.

Answer:4500 N
Explanation:
Given
mass of truck 
mass of car
as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck
and their acceleration is

Answer:
-2.79 m/s²
Explanation:
Given:
v₀ = 20 m/s
v = 11 m/s
Δx = 50 m
Find: a
v² = v₀² + 2aΔx
(11 m/s)² = (20 m/s)² + 2a (50 m)
a = -2.79 m/s²
Round as needed.
