2. A 10 Mg truck hauls a 20 Mg trailer. If the unit starts from rest on a level road with a
yanalaym [24]

Answer:

<em>The acceleration on the unit is 0.667 m/s^2</em>

<em>The tension on the draw-bar is 13.34 kN</em>

Step-by-step explanation:

The mass of the truck = 10 Mg = 10 x 10^3 kg

The mass of the trailer = 20 Mg = 20 x 10^3 kg

Tractive force from the truck = 20 kN = 20 x 10^3 N

The total mass of the unit = 10 Mg + 20 Mg = 30 Mg = 30 x 10^3 kg

The tractive force on the unit will produce an acceleration that is given as

F = ma

where

F is the tractive = 20 x 10^3 N

m is the mass of the unit = 30 x 10^3 kg

a is the acceleration of the unit = ?

substituting into the equation

20 x 10^3 = 30 x 10^3 x a

a = (20 x 10^3)/(30 x 10^3) = <em>0.667 m/s^2</em>

the tension on the draw-bar T is gotten from considering only the mass that is pulled by the draw-bar which is 20 Mg

The acceleration on the unit = 0.667 m/s^2

The drawn mass = 20 Mg = 20 x 10^3 kg

The tension on the draw bar = ma = 20 x 10^3 x 0.667 = 13340 N

= <em>13.34 kN</em>

the community food bank has 750 meals to distribute over a 12 hour period. They need to save at least 50 of the meals for the vo
Anit [1.1K]
Since we must save 50 meals for volunteers, the real amount we are giving away is 700 meals in 12 hours.

700/12 = 58.3333...

10*58.333.. = 583.333....

Since we can't serve 1/3 of a person, we take 583. Hope this helps!
