4. Far out in space, two rockets (140,000 kg and 170,000 kg) are docked at opposite ends of a rigid 20 m long connecting tunnel of negligible weight to the rockets. Both rockets start their engines of strength F, = 170 kN and F, = 180 kN, respectively. How long does it take for the system to reach 42 rev/min?

The United States possesses the ten largest warships in the world, aircraft carriers of the Nimitz class. Suppose one of the ships bobs up to float 11.0 cm higher in the ocean water when 50 fighters take off from it in a time interval of 25 min, at a location where the free-fall acceleration is 9.78 m/s2. The planes have an average laden mass of 29 000 kg. Find the horizontal area enclosed by the waterline of the ship.
When unable to loosen the lug nut on an automobile tire, a mechanic may put a piece of pipe on the handle of the tire wrench so as to extend its length. How does that help?
To get up on the roof, a person (mass 70.0 kg) places 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to frictionless. The center of ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.
Two stars of masses M and m, separated by a distance d, revolve in circular orbits about their center of mass (Fig. P11.50). Show that each star has a period given by T2=42d3G(M+m) Proceed as follows: Apply Newtons second law to each star. Note that the center-of-mass condition requires that Mr2 = mr1, where r1 + r2 = d.
A 51.6kg spacewalking astronaut pushes off a 630.0kg satellite, exerting a 119.0N force for the 0.283s it takes him to straighten his arms. How far apart are the astronaut and the satellite after 7.01min?
If object A has a mass of 63 kg and object B has a mass of 596,000,000 kg and the centers of their masses are 64m apart from each other. If there are no other measurable forces besides the gravity between them, then what will be the rate at which object A will accelerate? aA = ??? unit
Three identical small spheres, each of weight 2 lb, can slide freely on a horizontal frictionless surface. Spheres B and C are connected by a light rod and are at rest in the position shown when sphere B is struck squarely by sphere A which is moving to the right with a velocity v0 = (8 ft/s)i. Knowing that θ= 45° and that the velocities of spheres A and B immediately after the impact are vA = 0 and vB = (6 ft/s)i + (vB)yj, determine (vB)y and the velocity of C immediately after impact.

A light rod of length 2L is free to rotate in a verticalplane about a frictionless pivot through its center. A particleof mass m1 is attached at one end of the rod, and a mass m2is at the opposite end, where m1 >m2. The system is releasedfrom rest in the vertical position shown in Figure P8.84a, andat some later time, the system is rotating in the position shownin Figure P8.84b.

Johnny Manziel has decided that he’s a terrible quarterback (he’s pretty mad about it) andwants to become a kicker, but he’s concerned about the shoe he has chosen to kick withand how it will impact the inertia of his leg. The moment of inertia of the lower leg andfoot about an axis through the knee joint is 0.20 kg·m2. What is the moment of inertia ofthe leg and foot about the knee joint if a 0.50 kg shoe is worn on the foot? Assume thatthe shoe’s mass is all concentrated in one point 45 cm from the knee joint
