Two masses, m1 and m2 are separated by a distance, r. The force of attraction between the two masses is F. If the original force is 20N and both masses quadruple while the r decreases to ¼ of the original distance:
A) how much would F change?
B) what will be the new force?

A certain binary star system consists of two stars with masses m1 and m2, separated by a distance b. A comet, originally nearly at rest in deep space, drops into the system and at a certain point in time arrives at the midpoint between the two stars. For that moment in time, find its velocity, v, symbolically in terms of b, m1, m2, and fundamental constants. p

x2(t) m2 2 Two masses, m1 and m2, are connected with a spring, k. A force, f (t), is applied on the first mass. Both masses experience viscous damping, c1 and c2, through the surface that they sit on. The equations of motion that describe the system dynamics are m2 (t)--CzX2 (t)-k(X2(t)-x,(t)) The initial conditions are: x1(0) - a x(0)b (0) = c Assuming zero initial conditions, rearrange the two equations of motion to find the response for X1(s) and...

a. Two 700-kg masses (1543 lb) are separated by a distance of 33 m. Using Newton’s law of gravitation, find the magnitude of the gravitational force exerted by one mass on the other. (Use G = 6.67 × 10-11 N·m2/kg2.) (Round the final answer to four decimal places.) The magnitude of the gravitational force exerted by one mass on the other is ___________ × 10–9 N. b. Two masses are attracted by a gravitational force of 0.36 N. What will...
