Question 13
Your car is stuck in a mudhole, but you remember your physics. You tie one end of a long chain to a telephone pole, and the other to the axle of your car. Making sure the cable is as taut as you can make it, you push on the center of the cable with a 813 N force. When the angle θ = 7.47o , find the magnitude of the tension in the cable, in N, to just balance the applied force.

Your car is stuck in a mud hole. You are alone, but you have a long, strong rope. Having studied physics, you tie the rope tautly to a telephone pole and pull on it sideways at the midpoint, as shown. Find the force exerted by the rope on the car when the angle is 3.2 degree and you are pulling with a force of 395 N but the car does not move. Answer in units of kN. How strong must...

Problem #3 You've taken your neighbor's young child to the carnival to ride the rides. She wants LTU The Rocket. Eight rocket-shaped cars hang by chains from the outside edge of a large steel disk. A vertical axle through the center of the ride turns the disk, causing the cars to revolve in a circle. You've just finished taking physics, so you decide to figure out the speed of the cars while you wait. You estimate that the disk is...

Please show your work, thank you!
A 600-N uniform rectangular sign 4.00 m wide and 3.00 m high is suspended from a horizontal, 6.00-m-long, uniform, 110-N rod as indicated in the figure below. The left end of the rod is supported by a hinge and the right end is supported by a thin cable making a 30.0° angle with the vertical. (Assume the cable is connected to the very end of the 6.00-m-long rod, and that there are 2.00 m...

A toy car of mass 0.35 kg travels along a circular banked road, with banking angle 30°. The circle has radius 0.80 m. Sarah wants to make the car move as fast as possible, but if it goes too fast, it slips off the road. Therefore, Sarah cuts a 0.80- meter piece of string, attaches one end to the car, and attaches the other end to a nail stuck in the center of the circle. Unfortunately, the string is thin...
