The dogs of four-time Iditarod Trail Sled Dog Race champion Jeff King pull two 100-kg sleds that are connected by a rope. The sleds move on an icy surface. The dogs exert a 240-N force on the rope attached to the front sled. The front rope pulls horizontally.
Part A
Find the acceleration of the sleds.
Express your answer to two significant figures and include the appropriate units.
Part B
Find the force the rope between the sleds exerts on each sled.
Express your answer to two significant figures and include the appropriate units.

Answer:

Part a)

[tex]a = 2.4 m/s^2[/tex]

Part b)

[tex]F = 120 N[/tex]

Explanation:

Two sleds are connected by a rope

mass of each sled is given as

[tex]m = 100 kg[/tex]

now we know that dog exert pulling force on the rope connected to first sled

[tex]F = 240 N[/tex]

Part a)

By newton's first law we know that

[tex]F = (m + m)a[/tex]

[tex]240 = (100 + 100)a[/tex]

[tex]a = \frac{240}{100}[/tex]

[tex]a = 2.4 m/s^2[/tex]

Part b)

As we know that force between two ropes will pull the sled behind

so we will have

[tex]F = ma[/tex]

[tex]F = 100(1.20)[/tex]

[tex]F = 120 N[/tex]

Answer:

Answer:

(a) acceleration a = 1.2m/s2

(b) force F = 100N on each sled
