## Homework Statement

A 2200kg airplane is pulling two gliders, the first of mass 310kg and the second of mass 260kg, down the runway with an acceleration of 1.9m/s^2. Neglecting the mass of the two ropes and any frictional forces, determine the tension force in the second rope.

## Homework Equations

F=ma

## The Attempt at a Solution

This is what i have done, however i do not understand the book's answers.

Two forces acting on rope 2, so...

T-494 = 4180

T=4674N

book's answers is 494N, wouldn't this be the net force on the second glider??

## Homework Statement

A child pulls an 11kg wagon with a horizontal handle whose mass is 1.8kg, giving the wagon and handle an acceleration of 2.3m/s^2.

a) Find the tension at each end of the handle?

## Homework Equations

F=ma

## The Attempt at a Solution

Can someone check if my answer is correct.

Net Force of Handle and Wagon are:

F=4.14N and F=25.3N

Tension from handle to wagon

T1-4.14 = 25.3

T1=29.22N

Tension from wagon to handle

25.3-T=4.14

T=20.89N

## Homework Statement

In a tractor pulling contest, a 2300kg trctor pulls a 4900kg sledge with an acceleration of 0.61m/s^2. If the tractor exerts a horizontal force of 770N on the ground, determine the magnitude of

a) the force of the tractor on the sledge.

b) the force of the sledge on the tractor and

c) the frictional force exerted on the sledge by the ground.

## Homework Equations

F=ma

## The Attempt at a Solution

Like the last question can someone tell me if my answer is correct, if not what have i done wrong?

a)Fnet = ma

T - Fnet = ma

T - 7700 = 2300 * 0.61

T - 7700=1403

T=9103N

b) Fnet = ma

T - Fnet = ma

T - 48020 = 4900 * 0.61

T=51009N

c)

T - Friction = ma

9103 - Friction = 4900 * 0.61

Friction = 6114N
