The total mechanical energy would be flat. As the potential energy decreases, the kinetic energy increases, and this keeps the mechanical energy at a constant value. Kinetic energy would be increasing. The potential energy is turning into...

The time is t = { arccos(sqrt(x/d)) + sqrt((x/d)*(1-x/d)) } * d^1.5 / sqrt (2 mu) with x = final separation = sum of radius of the two planets d = initial separation mu = G * sum of the two masses.

Not sure whether you want the answer from classical Newton plus special relativity or just general relativity. From the classical Newton gravity standpoint where we can treat gravity as just another force, plus special relativity, we can simply use the relativistic energy-momentum equation where the change in both the time...

To keep the car in a circle at any given speed we need a centripetal acceleration of v^2 / r = 4^2/523 To accelerate the car along a path we require an acceleration = dv/dt = (44.4-0)/12.8 As both accelerations are perpendicular to each other the resultant lies on some angle between...

F = ma If we let F = force of one rocket Ff = friction force 4F - Ff = ma F = (ma + Ff) / 4 so the force for each rocket F = (1615(57.0) + 430) / 4 F = 23,121.25 N With only one rocket firing a = F / m a = (23,121.25...
