Simple.
1 mile = 1.6 km
So simply, 20,000 miles = 20,000 × 1.6
which is equal to 32,000km
Hope it helps dear friend ☺️
Answer:
Explanation:
first pilot moved 62.6 miles west towards another airport
so we have
now at that airport it fly again 28.9 miles at 15 East of South
so we have
now net displacement of the plane is given as
magnitude of the displacement is given as
The awnswer is c give me brainlest!!!
Answer:
k = 9.6 x 10^5 N/m or 9.6 kN/m
Explanation:
First, we need to use the expression to calculate the spring constant which is:
w² = k/m
Solving for k:
k = w²*m
To get the angular velocity:
w = 2πf
The problem is giving the linear velocity of the car which is 5.7 m/s. With this we can calculate the frequency of the car:
f = V/x
f = 5.7 / 4.9 = 1.16 Hz
Now the angular velocity:
w = 2π*1.16
w = 7.29 rad/s
Finally, solving for k:
k = (7.29)² * 1800
k = 95,659.38 N/m
In two significant figures it'll ve 9.6 kN/m
