Answer:
0.882 m/s average velocity and 1.71 m/s average speed
Explanation:
The dog travels a total of 35 m west and 110 m east.
110-35 = 75 m east of the starting position. Since velocity is a vector you must consider its first and final position and not the total distance traveled.
75 m / 85 s = 0.882 m/s average velocity
Speed is not concerned with direction so we instead add the total distance traveled which is 35+110 = 145 m. We then perform the same operation as before and divide by the time it took to run this distance.
145 m / 85 s = 1.71 m/s average speed
Hmmm... I’d say that’s pretty accurate. Good job! Well wishes on whatever it is you’re doing.
at t=T/6, total distance covered= 2*pi*r/6 and displacement= r
difference of them = 2*t
so, 2*pi*r/6- r =2(1/6)=1/3
r=1/(pi-3)=7.062
Answer: 200 joules I think.
Explanation:
e = 0.57 is the moon's orbital eccentricity
You may determine the ellipse's eccentric formula by using
e = r a - r p / r a + r p
The distance r a between the moon and its planet is the greatest.
r p=0.27 The shortest distance between the moon and its planet is r a.
Then, e = r a - r p / r a + r p
e is defined as (r a - 0.27 r a) / (r a + 0.27 r a).
e = 0.73r a / 1.27 r a
e = 0.57
The eccentricity of a conic section expresses how much it resembles a circle. Every conic section has this distinctive parameter, and conic sections are only said to be identical if and only if their eccentricities are the same. A conic section's eccentricity is a non-negative real integer that specifically describes its shape. Formally speaking, two conic sections are comparable if and only if their eccentricities match. The eccentricity can be thought of as a measurement of how far a conic section strays from being round.
