Chapter 4: Problem 70

A towline is attached between a car and a glider. As the car speeds due east along the runway, the towline exerts a horizontal force of \(850 \mathrm{N}\) on the glider. What is the magnitude and direction of the force exerted by the glider on the towline?

Short Answer

Expert verified
Answer: The magnitude of the force exerted by the glider on the towline is 850 N, and the direction is towards the west.

Step by step solution

01

Recall Newton's Third Law of Motion

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. In other words, the forces exerted by two objects on each other are always equal in magnitude but have opposite directions.
02

Determine the magnitude of the force exerted by the glider

Since the force exerted by the towline on the glider is 850 N, by Newton's Third Law, the force exerted by the glider on the towline must have the same magnitude. Therefore, the magnitude of the force exerted by the glider is 850 N.
03

Determine the direction of the force exerted by the glider

As previously mentioned, the forces exerted by two objects on each other have opposite directions. So, if the force exerted by the towline on the glider is directed towards the east, then the force exerted by the glider on the towline is directed towards the west.
04

State the magnitude and direction of the force exerted by the glider

The magnitude of the force exerted by the glider on the towline is 850 N and the direction is towards the west.

While an elevator of mass 832 kg moves downward, the tension in the supporting cable is a constant \(7730 \mathrm{N}\) Between \(t=0\) and \(t=4.00 \mathrm{s},\) the elevator's displacement is \(5.00 \mathrm{m}\) downward. What is the elevator's speed at \(t=4.00 \mathrm{s} ?\)
A roller coaster is towed up an incline at a steady speed of $0.50 \mathrm{m} / \mathrm{s}$ by a chain parallel to the surface of the incline. The slope is \(3.0 \%,\) which means that the elevation increases by \(3.0 \mathrm{m}\) for every \(100.0 \mathrm{m}\) of horizontal distance. The mass of the roller coaster is \(400.0 \mathrm{kg}\). Ignoring friction, what is the magnitude of the force exerted on the roller coaster by the chain?
A cord, with a spring balance to measure forces attached midway along, is hanging from a hook attached to the ceiling. A mass of \(10 \mathrm{kg}\) is hanging from the lower end of the cord. The spring balance indicates a reading of \(98 \mathrm{N}\) for the force. Then two people hold the opposite ends of the same cord and pull against each other horizontally until the balance in the middle again reads \(98 \mathrm{N} .\) With what force must each person pull to attain this result?
A 50.0 -kg crate is suspended between the floor and the ceiling using two spring scales, one attached to the ceiling and one to the floor. If the lower scale reads \(120 \mathrm{N},\) what is the reading of the upper scale? Ignore the weight of the scales.
A block of mass \(m_{1}=3.0 \mathrm{kg}\) rests on a frictionless horizontal surface. A second block of mass \(m_{2}=2.0 \mathrm{kg}\) hangs from an ideal cord of negligible mass that runs over an ideal pulley and then is connected to the first block. The blocks are released from rest. (a) Find the acceleration of the two blocks after they are released. (b) What is the velocity of the first block 1.2 s after the release of the blocks, assuming the first block does not run out of room on the table and the second block does not land on the floor? (c) How far has block 1 moved during the 1.2 -s interval? (d) What is the displacement of the blocks from their initial positions 0.40 s after they are released?
