(superposition, quadratic formuła) the earth (mass m) is at origin, and the moon (mass m ) is located at a distance d. (a) using newton's law of gravitation f, find the total gravitational force acting on a spaceship (mass m) at r. (b) find the location(s) where this force vanishes, assuming that d -380,000 km. 17. (differentiation, integration) what distance do you cover in the x-direction per unit time if your speis given by: (a) ?
