Refer to the diagram shown below.
The given data is
mass, kg Coordinates. m
------------- -----------------
2 (0, 0)
2 (2, 0)
4 (2, 1)
Total mass, M = 2+2+4 = 8kg
Let (x,y) be the coordinates of M.
Then, taking moments about the origin, we obtain
8x = 2*0 + 2*2 + 4*2 = 12
x = 1.5 m
8y = 2*0 + 2*0 + 4*1 = 4
y = 0.5 m
Answer: (1.5, 0.5) m
Explanation:
It is given that,
Density of asteroid,
Mass of asteroid,
We need to find the diameter of the asteroid. The formula of density is given by:
V is the volume of spherical shaped asteroid,
r = 2441311.12 m
Diameter = 2 × radius
d = 4882622.24 m
or
Hence, this is the required solution.
Answer:
The magnitude and direction of its angular momentum relative to point is 115.28 kg m²/s.
Explanation:
Given that,
Mass = 2.00 kg
Velocity = 12.0 m/s
Suppose the distance from point O to point p and angle is 8.00 m and 36.9°.
We need to calculate the magnitude and direction of its angular momentum relative to point
Using formula of angular momentum
Where, r = distance from point O to point P
v = speed
= direction
Put the value into the formula
The direction of angular momentum is pointing into the page.
Hence, The magnitude and direction of its angular momentum relative to point is 115.28 kg m²/s.
