Two people play tug of war. The 100-kg person on the left pulls with 1,140 N, and the 70-kg person on the right pulls with 835 N. Assume that neither person releases their grip on the rope with either hand at any time, assume that the rope is always taut, and assume that the rope does not stretch. What is the magnitude of the tension in the rope in Newtons?

A spring lies on a horizontal table, and the left end of the spring is attached to a wall. The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move. The mass of the box is 0.75 kg, and the spring has a...

I have a strong spring attached to a wall that has a spring constant of 700 Newtons per meter. Our trusty assistant Ed pulls on the spring and stretches it a distance of 20 centimeters. You then take over from that point and pull to stretch the spring 10 more centimeters so that it is stretched 30 centimeters total from the beginning. Calculate the work done by Ed and the work done by you in this process. At time t...

10pts A uniform beam is attached at its left end to a wall. The beam sticks out horizontally from the wall. At the right end of the beam is a wire that stretches back to the wall at an angle of 33° above the horizontal. The tension in the wire is 127N. Also attached to the right end of the beam is a hanging mass of 5.0 kg. What is the mass of the beam in kg? O 21 09.1...

A spring sits on a frictionless horizontal surface, one end of the spring is attached to a wall, the other end to a mass M, (M sits on the same surface). One delivers a blow to the mass in such a way so as to stretch the spring, The mass comes to momentary stop 3 seconds later. If the mass is 2 kg, what is the spring constant k? Show and explain all your work.

A 1400-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Using the data shown in the figure, find (a) the magnitude of the tension in the wire and the magnitudes of the (b) horizontal and (c) vertical components of the force that the wall exerts on the left end of the beam.

A uniform bar of length 3.2m and mass 4.4kg is attached to a
wall through a hinge mechanism which allows it to rotate freely.
The other end of the bar is supported by a rope of length 5.7m
which is also connected to the wall as shown above. What force in N
does the wall exert horizontally on the bar through the hinge?
(Consider a force to the right positive and a force to the left
negative.) see image below....
