Answer:
Explanation:
It is given that,
The coordinates of a particle in the metric xy-plane are differentiable functions of time t are given by :
Let D is the distance from the origin. It is given by :
Differentiate above equation wrt t as:
.............(1)
The points are given as, (12,5). Calculating D from these points as :
Put all values in equation (1) as :
So, the particle is moving away from the origin at the rate of 7.076 m/s. Hence, this is the required solution.
Answer:
√3 * Gm²/d²
Explanation:
m1 = m, m2= m, distance = d. hence:
F = Gm²/d²
Let the origin be A, the point x = d be B and the point above the first two is C.
The net force acting on the third mass (point C) =
Let j represent the vertical component and i the horizontal component. Hence:
