Altitude is the angle measured above the horizon
Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Π / (4200 Π) = 8.2 laps
A will make 8 but not 9 rounds before catching B
The Milky Way in the sky is our particular view of the inward part of the Milky Way Galaxy as seen from our location within the Galaxy's disk. Since we are part of the disk, we see a band of diffuse light that completely encircles us.
Use the formula,
where 
is the cart's displacement (from the origin), 
is its initial speed, 
is its acceleration, and 
is time.
Alternatively, since acceleration is constant, we have
That is, we have these two equivalent expressions for average velocity, where 
is the cart's final velocity. Solve for :
