Two boats, each with a mass 140.0 kg and length 4.00m are just touching each other. There is a gap between boat #1 and a wall that is 1.5 m. A man (70.0 kg) standing on boat #1 decides to step onto boat 2. As a result, both boats start to move. When boat #1 hits the wall, how far are the two boats separated?

The two slender bars each of mass m = 4.6 kg and length b = 700 mm are pinned together and move in the vertical plane. If the bars are released from rest in the position shown and move together under the action of a couple M = 16 Nom of constant magnitude applied to AB, determine the velocity of A as it strikes O. Initially the angle 0 = 24º. B ele B M Answer: VA = m/s
Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other
Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...

QUESTION 1 Two skaters, one of mass 80 kg, the other of mass 40 kg, are standing next to each other on frictionless ice rink. The 40 kg skater pushes the 80 kg skater. After the push, the 80 kg skater is going at 1 m/s. How fast and in what direction is the 40 kg skater going after the push? (HINT: use the fact that since there are no external forces, the velocity of the center of mass of...

1) Two red blood cells each have a mass of 9.05×10−14 kg and carry a negative charge spread uniformly over their surfaces. The repulsion arising from the excess charge prevents the cells from clumping together. One cell carries −3.00 pC and the other −3.30 pC, and each cell can be modeled as a sphere 3.75×10−6 m in radius. If the red blood cells start very far apart and move directly toward each other with the same speed, what initial speed...

Two balloons each have mass 4.0x10 kg. Balloon 1 has a negative net charge. Balloon 2 has twice the net negative charge of balloon 1. Balloon 1 is taped to the wall, and balloon 2 is tied to a string of length 0.70 m, which is attached to the ceiling directly above balloon 1 as shown. In the final equilibrium situation, the string makes a 20 degree angle away from balloon 1, and the two balloons are at the same...
