A car of mass 1300 kg is towed at a steady speed by a cable held at an angle of 20° above the horizontal. A frictional force of 500 N opposes the motion of the car. Find the tension in the cable
Homework Answers
here,
mass of car , m = 1300 kg
theta = 20 degree
frictional force , ff = 500 N
let the tension in the string be T
as it is moving at constant speed
the net force in horizontal direction is zero
so,
T * cos(theta) - ff = 0
T * cos(20) = 500
T = 532.1 N
the tension in the string is 532.1 N

A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...

A box (m 60 kg) is held in position on an incline by a cable. The incline makes an angle of 60° with the horizontal. The coefficients of friction between the surface and the box are us 0.400 and H-0.300. (note: ignore the force on top of the box until part C) Find the normal force exerted by the incline Find the tension force in the cable If the cable were to break, find the necessary force needed to be...

A 1160-kg car is being pulled up a frictionless ramp at a constant speed, as shown in the figure
A 1160-kg car is being pulled up a frictionless ramp at a constant speed, as shown in the figure. (Figure 1) The cable makes an angle of 31.0° above the surface of the ramp, and the ramp itself rises at 25.0° above the horizontal. Find the tension in the cable How hard does the surface of the ramp push on the car?

A 750 kg car slows to a stop from traveling southbound at 30 m/s over a distance of 500 m. What was the acceleration needed to stop the car? How large was the force required to stop the car? Two cables are being used to pull a 100 kg sled on a frictionless surface. The first cable has a tension of 500 N in a direction 15o south of east. The other cable has a tension of 800 N in...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
