Two passengers with masses MR=30 kg and ML=50 kg are standing on the two ends of A boat with mass Mb=120 kg. The length of the boat is L=10 m and its center of mass is in the middle of the boat

a) The two passengers start running toward each other with equal speeds u=1 m/s relative to the boat. With what velocity V=? does the boat start moving?

b) After the two passengers reach each other at the center of the boat, how far d=? has the boat moved?

c) If instead of running toward each other, passenger with mass MR=30 kg does not move and the other passenger with mass ML=50 kg move and meet him at the other end of the boat, how much d’=? has the boat moved?

Leo and Alex, with masses of 100 kg and 50 kg, are holding opposite ends of a rope. They are standing on the middle of a frozen lake, where friction is negligible. They are standing 6m apart. Leo gives the rope a pull – 100 N – for one second. Let’s call the start of this pull t=0. a) What is their subsequent motion? On a position-vs-time graph, plot the position of both of them over time. b) Do they...

Two masses, mA = 32.0 kg and mB = 41.0 kg are connected by a rope that hangs over a pulley (as in the figure(Figure 1)). The pulley is a uniform cylinder of radius R = 0.316 m and mass 3.4 kg . Initially, mA is on the ground and mB rests 2.5 m above the ground. a.If the system is now released, use conservation of energy to determine the speed of mB just before it strikes the ground. Assume...
