A person with mass m1 = 61 kg stands at the left end of a uniform beam with mass m2 = 104 kg and a length L = 2.6 m. Another person with mass m3 = 68 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 8 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate...

A 45.0-kg
woman stands up in a 60.0-kg
canoe 5.00
m long. She walks from a point 1.00
m from one end to a point 1.00
m from the other end (the figure (Figure 1) ).
Part A
If you ignore resistance to motion of the
canoe in the water, how far does the canoe move during this
process?
dcanoe =
m to the left
A scaffold of mass 44 kg and length 5.1 m is supported in a
horizontal position by a vertical cable at each end. A window
washer of mass 73 kg stands at a point 1.5 m from one end. What is
the tension in (a) the nearer (relative to the
person) cable and (b) the farther (relative to the
person) cable?
A 30-kg child stands at one end of a floating 20-kg canoe that is 5.0-m long and initially at rest in the water. The child then slowly walks to the other end of the canoe. How far does the canoe move in the water, assuming water friction is negligible? Please show step by step and explain.
A person with mass m1 = 63 kg stands at the left end
of a uniform beam with mass m2 = 91 kg and a length L =
2.7 m. Another person with mass m3 = 59 kg stands on the
far right end of the beam and holds a medicine ball with mass
m4 = 15 kg (assume that the medicine ball is at the far
right end of the beam as well). Let the origin of our coordinate...
A scaffold of mass 75 kg and length 5.5 m is supported in a horizontal position by a vertical cable at each end. A window washer of mass 79 kg stands at a point 2.4 m from one end. What is the tension in (a) the nearer (relative to the person) cable and (b) the farther (relative to the person) cable? (a) Number Units (b) Number Units
034 10.0 points A 98 kg boat that is 6.4 m in length is initially 7.4 m from the pier. A 45 kg child stands at the end of the boat closest to the pier. The child then notices a turtle on a rock at the far end of the boat and proceeds to walk to the far end of the boat to observe the turtle. 7.4 m 6.4 m How far is the child from the pier when she...
A toy car that is traveling on a horizontal dock with a speed of 3.00 m/s when it comes to the end of the dock and proceeds to fall into the lake below. 1) The toy car splashes in the lake below 0.639 seconds later. How high above the water is the dock? a) 0.639 m, b) 1.00 m, c) 2.00 m, d) 4.00 m, or e) 6.26 m 2) If the car had been dropped from rest at the...
3) A uniform horizontal beam of length 12.0 m and a mass of 20 kg is attached to a wall. Its far end is suspended by a cable that makes an angle of 63 degrees with the beam. A person of mass 72 kg stands a distance d = 4.0 m from the wall. Find the tension in the cable as well as the magnitude and direction of the force exerted by the wall on the beam.
The figure shows a uniform, horizontal beam (length = 10.0 m, mass = 30.0 kg) that is held by a horizontal pin (pivoted at the wall), with its far end supported by a cable that makes an angle of 51 degree with the horizontal. A person of mass M stands 3.00 magnitude of 454 N. (a) Calculate the mass M of the person standing on the beam? (b) What are the horizontal and vertical components of the force the pin...
